I'm a senior female traveller heading to Cuba alone for about 3 weeks in Feb 2011.....I need some advice on good Casas and travelling , I'm going to Havana, Trinidad and ending up in Varadaro or somewhere else

Casa particulars are the way to go. Just ask around, especially the taxi drivers. They all know where the good ones are and can help out. I'm not too keen on Varadaro. It's a place for packaged tourists who just sit on the beach and take hotel sponsored trips out of the "compound". Locals are not allowed to enter the hotels there. How about Cienfuegos? Not a bad little town.
Get ready for some really bad food. We rented a car for a week during our last trip and just cruised around. Great fun.

Cuba is not an easy country to get around in. They are lovely,passionate people but,probably through desperation (life is very hard )it seems everyone who talks to you will have some scam going. We've been to almost every country especially Asia, but this was one country our research showed, is better done with a small group tour and for the first time ever we did with Gap/Intrepid. After the first few days on our own in Havana we were SO glad we did. We saw folks waiting days at bus stops and stations and being ripped off everywhere. The tour was 10 interesting people, we had our own transport and got to every interesting spot, staying in Casas and being shown great food and places we could never have found - including secret music spots and dance venues .The population generally lives on bad ham rolls and pizza slices. Do yourself a huge favour - I'm sure it cost no more!

Excellent point. My first trip was with a friend who had been 2-3 times before, and had a good buddy who lived in Havana. And he spoke perfect Spanish. Scams galore. Don't believe a word any of them say. I hate to say that, but you really have to be careful. We encountered scams everyday...but luckily, knew what was going on.
It's the only place I've ever been where I ate a chicken sandwich that was 90% skin and fat. Sick. But had no choice.
I stayed in Varadero last year and seem to remember there weren't any casa particulares there at all. I don't normally tend to do package holidays but I did for Cuba because it just seemed so much easier, and at that particular time what I really needed was a relaxing beach holiday. We stayed in an all inclusive resort which meant we had great food and spent most of our time on an amazing beach. Although rather than going on one of the trips to Havana which was organised by our hotel, my friend and I made our own way there by bus and then checked into one of the budget hotels listed in the Lonely Planet guide. Havana is a fascinating city.
I agree with the comments above - Cuba not a very easy country to get around in. Sorry I can't help you more, but I wish you a great trip!
Agree with all the posters above. We (my husband and I) were there five years ago for a month. Havana, Trinidad, Cienfuegos (sp?) Santa clare and .. I forget. For sure, It's NOT an easy country to get around independently. We often got cheated or ripped off. Listen to Tom Kat. Book a tour. He is so right!

I agree totally with Tom Kat - a tour for at least part of the time is a great way to go, especailly for any travelling you want to do. Even hiring a car can be somewhat problematic.
But for the rest of the time eg in Havana itself, you can find and book casa particulares or hotels through the internet. Of course we arrived in Havana and were very kindly picked up by our host, the chap we had booked through ... but it turned out the house we had booked was no longer available (surprise?) and he took us to another somewhere nearby. It was ok but clearly a bit of a scam too... but then we could have left and found another one for ourselves.
Havana is totally amazing - every street a delight. We would wander for hours and hours - don't miss the art gallery - very moving! Oh and take in a show at the Gran Teatro - everyone dresses up and it's wonderful. We were lucky enough to catch a modern dance company who are apparently world famous (we had no idea) and they were fantastic.
What I love most is wandering in a town like Santiago just listening for music and then following the sound to find a great jam session or old people dancing in a square... just take a few snacks for when there is nothing you can eat.

Two of us - 60-ish women - spent two weeks there last month, and found it quite easy to get around. Admitedly, my Spanish is pretty good (but far from perfect), which allowed us to interact a lot more. We started with an internet arrangement with a guide/travel agent who reserved 3 nights in a casa in Havana Vieja. After that we relied on each casa owner to refer us to a next casa in the next town. We travelled by Viazul bus to Vinales, Matanzas, Varadero (just for a lark) and back to Havana.
Jorge (jorgeguide2004@gmail.com) arranged our first casa and a taxi to meet us at the airport. (I recommend that approach.) We actually met him in person briefly at the casa on the third day when he had come for some arrangement with an Australian couple, so I know he is real. He replies very promptly to emails, and I'd happily use him again. I've read a recent comment about his tour prices being a bit high, but after my visit and experiencing other tours and options, I don't think his prices are unreasonable. Cuba is not really a cheap country, except the casas are a bargain.
Yes, the Cubans are always trying to earn money from tourists, and there are scams (women on the street wanting us to buy milk for her children at a market, presumably using convertible pesos that she'd get a cut on). However, most of the time they are very honest and simply trying to make a living. Of course one must never abandon caution, but I sometimes had to remind myself not to be automatically suspicious. In fact the Cubans were 99.9% wonderful. I don't view it as a scam if the casa turns out to be full and they suggest another place. In fact, because they can't get payment in advance, they are vulnerable to having "no shows" and it doesn't surprise me that they accept someone else who shows up. The network of referrals and even having "agents" at the bus station are the interesting parts of the Cuban experience, so please don't view them as scams.
It is correct that Varadero has no casas particulares. However it does have some cheap hotels just a few blocks from the bus station. Varadero might be great for a lazy beach holiday but it is not at all interesting.
I never considered renting a car - too many unknowns and risks. Besides, I liked the buses. Viazul buses are comfortable and the drivers were professional.
Here are 3 casa recommendations:
Casa Habana in Habana Vieja - Emilio Nodarse Valdes - His card says enovalh@yahoo.es but Jorge made the initial reservation for us.
Casa Nenita in Vinales - emiliadiaz2000@yahoo.es - Refered by the people at Casa Habana. It was excellent.
Villa Encanto in Matanzas - victor64jo@yahoo.es - A fellow at the bus station took us there and it turned out to be very good.
Have fun!
I've been in Cuba as a solo female traveller 3 times and had a great time every time! I definately don't agree with the poster who says the only way is to go on an organised tour, the third time I got a cheap deal in Varadero and even had a great time there cos I found the local music bars, also went to some local places in Havana where I was the only tourist, it's just how open you are to meeting up and moving with the locals, I found the Cubans very warm and friendly (and my spanish is very basic).
Next time I plan to travel round the island.

Enjoy it!
