The apartment was good, great location, so clean and nice place to stay. It is really close to the train station and the aqua transport.
The only thing that it could be better it's about the adventure to find the keys, because at night it's dark and a bit far from the apartment, so you better have some extra time (about 15 minutes) if you have some tour booked. My recommendation, if you travel in group, it's to find the apartment first, leave the luggage with some and go find the keys.
Everything else was perfect, Venice it's a great place to visit and the apartment had more that everything we needed, you would like it
