The apartment looked just like it did in the pictures: very clean, convenient to San Marcos square (5 minute walk!) Perfect for our family of 4; our 2 older kids shared the room with the single beds and the 2 bathrooms were clean and well stocked with everything we needed! Air conditioning and Wifi worked great. We loved the windows that overlooked the canal and the gondolas going by. It was a gondola stop and unfortunately a trash stop in the early morning, so could be a bit loud, but we are all sound sleepers so it didn't bother us (something to be aware of if you are awakened easily by noise). The Church of Santa Maria Formosa was directly across the canal from us and I loved the fact that you could see the church steeple and we could easily locate our apartment when looking at views of the city from the Campanile!
The host Mario always responded quickly to my e-mails, and gave lots of helpful information. We got in late (try not to arrive after 8 pm since it will cost 60 euro) and Paulo was nice enough to meet us at the vaporetto at 11:15 pm and walk us to the apartment so we wouldn't get lost.
I would definitely stay in this apartment again!
