We loved this apartment for our visit to Venice. The location is great and in a quieter part of Venice, while also not too far away from the train station and main attrations. There are also a few restaurants and bars nearby. We slept with the windows closed and with fans to keep cool, and we couldn't hear any late night noises.
The host is really lovely and considerate. Upon request, he met us at the train station and led us to the apartment, and also provided us with advice on where to go, the nearest supermarket and church times etc.
We were 4 people - one couple had the master bedroom and the other couple slept on a pull out couch in a separate room. The couch bed wasn't prepared when we arrived, but the host had laid out the bedding and we were happy to do that ourselves. According to the couple who used the couch bed, it wasn't super comfortable - with a bit of a ditch in the middle - but it was fine for a few nights.
