Our family of 4 with 2 teenagers stayed for 3 nights in March. The apartment is in a very central and convenient location. As per Yanet's direction, we took the water bus and met Luca at the stop who took us to the apartment (thanks very much). The apartment is 3 mins to the water bus stop and 5 mins from Rialto bridge, and very close to all the other attractions. It's just in a perfect location. Also very quiet.
Yanet and Luca are very responsive to our questions. If necessary, you could check out and then leave the luggage until it's your train time.
There is one bedroom and a sofa bed in the living room. The kitchen is adequate for cooking light meals. Everything is clean.
