The flat is located near San Marco and it is overall on a very good spot. Everything is clean and tidy. You have 2 bathrooms to use which is really convenient, since you will be living with many other people. Well-equipped kitchen and spacy bedrooms with fans included. There is even a computer free to use. The only problem was to contact my host before arrival.
I really fell in love with this place. You can meet and talk to many people from all over the world and share your experiences with them. And when you wake up, don't forget to look down from your window - you might see a gondola making its own way just a few metres below.
PS: Do not try to find the adress through Google! Just don't!
