We stayed in this Apt for 3 nights in August 2015. This is a large Apt that is centrally located in Venice. Carlo met us at the water taxi stop and we walked to the Apt- a nice 5-10 minutes walk. One room has very nice AC, the other room has a portable AC- hot air enters the room since the vent is place at the door and can not close the door. This is a historic building and Carlo explained that it is difficult to get permit to add AC.
From windows there is a nice view of a bridge and you can see gondolas passing by.
Hot water only lasted for a few minutes which was not adequate for 5 people.
At onset you are warned about the lock on black security door that the key may get stuck if not used properly. This happened to us and we had to call the fire department to open the door in the middle of night! Best if you do not lock this door at all. We stayed in 2 other Apts in Rome and Florence and they had similar lock and key and we never had any problems.
We enjoyed our stay but would not use this apt during hot August month.
