This is a wonderful place to stay and Chiara is an incredible host. The apartment is beautiful and a wonderful place to stay, but Chiara'shospitality made our visit extra special. A friend and I stayed and I took the smaller bed. It was big enough for me. I am 5'6" and weigh 192 lbs, so it is definitely big enough for an adult.
Chiara was available to contact at anytime and met us at the boat station. She personally walked us to the apartment, gave us a map, spent time telling us the best things to do and places to go. We arrived a day late because of a train problem and she refunded the night, even though she really didn't have to.
I can't say enough good things about the apartment and Chiara. This is the only place we would stay in Venice.
