Sant Jordi- la sagrada de la familia, it is an apartment style hostel and u can book your own room or share one room with another person, i thought it was geat and it also had free laundry.

For #10: I think it all depends on what you're looking for. I think many people, especially those who travel by themselves, need hostels that are social in order to find others to see the sites with. If you are comfortable being on your own, or if you are with a group of people who don't wish to interact, than an HI is probably a better choice.

OP - Yes, Hostelling International hostels are good. Website: www.hihostels.com.<BR><BR>Last year my daughter and I stayed in a female dorm at the HI hostel in Lisbon, shown as 'Lisbon - Centre' on the site. Currently they have beds @ 16 euros per person per night. Excerpt from the site: "Bed(s) in Dorm female, Sheets included, Breakfast included, male/female rooms (not coed) 16.00 EUR (per night, per bed)". Well-located.
Do carry a small lock that you can use for the locker in the dorm for your valuables; the lockers were quite spacious - about 1.5 ft for each dimension from what I can remember.
