The service in general was very professional and hosts were kind. Location is good, close to San Marco (but not so close to other areas) but more calm and with fewer tourists, which was quite nice. The apartment is quite nice, very well equipped, super clean and in a quite area. Heating system also works well. Potential improvement: the bed sofa was not so comfortable in the case of 4 people. There was some noise in the water boiler during the evening but I assume this is typical in Venice apartments. In the last day I have forgotten a personal belong and hosts were super kind to give me back in some other day, which I really appreciate. Anyway, I would recommend the place and come back again.
