My wife and I last went to Venice in the summer of 2013 and really enjoyed it but not how busy and hot it got so it was a nice surprise to see Venice so quiet!
The place is really cute, the window feature to the canal is unique. I quite liked sleeping on a mattress, ironically it was comfier than a hotel bed.
The flat was kept warm for us at all times but is recommend slippers as the floor can get really cold!
The flat is literally 2 minutes from a vaporetto stop (Gigilo) which is roughly around 35 min or so to the first stop when you come from the airport or train station. Marco polo is also less than 5 min walk so very centrally located. Is definitely recommend this place specially in better weather so you could enjoy the amazing canal views of gondolas passing by and lovely gondola men singing beautifully.
