House rent on Dalmatian Riviera

Am looking for a charming villa to rent with three comfortable double rooms for a reunion with old univ pals next year. We are celebrating our 50th birthdays and want to get together for a week and cook, drink, swim, do some sightseeing, swim again, and basically chill out. I have been told by a kind TT user that the Dalmatian coast has plenty to offer; only problem is when I searched it on the internet, so many places come up and I just dont know anything about them. I would be really grateful if someone could make a recommendation, either for a house, villa, or good website with user friendly info. Many thanks!
