Ana Maria's is a great place for discovering Venice! It is actually a bed and breakfast more than a traditional airbnb. It is VERY conveniently located, only 5 minutes by foot from Piazza San Marco and many other central sights. The place itself is beautifully furnished and very clean. I felt very much at home during my two nights stay at her place; except for church bells ringing the place is very quiet and I slept extremely well. The host is exceptionally kind and welcoming. She greeted me when I arrived in the evening and was also present in the mornings to serve a little breakfast. I very much recommend staying at Ana Maria's place and will certainly come back there the next time I travel to Venice!
