Great location. Only a few minutes to Rialto bridge, but still very, very quiet. Big apartment, which is unusual for Venice. We stayed there with 4 people and there was plenty of room. However, if you are staying there with more, you have to take into account that there is only one bathroom. Kitchen is stocked with everything you need.
Wifi worked perfectly. As with most apartments in Venice, there was a typical "wet" smell, but it was only noticeable when entering the apartment. After 2 minutes you won't even notice. Horacio was very easy to contact, when we had a question.
