The place was clean and orderly and the hosts were so friendly and helpful. If you just ask, they will give you amazing suggestions on where to go, what to try. Just tell them what you're looking for (pizza, something cheap, what to check out) and they show you the way, map and all!
Even though you don't have to socialize, they do foster this nice environment that allows you to just hang out with other guests if you want -- the living room and the kitchen were common areas. I was able to talk to different people from different places and it was a really cool experience. There is a quiet time past 10pm, so we had to keep it down.
The location of the place is also just exquisite. It is so close to the square that I did not have to worry about a long, tiring travel at the end of the day, because the San Marco Plaza is pretty much in the heart of most places I wanted to hit that day. Overall, a great experience and one of the most memorable trips I've had and this place played a big part in it.
