Very good location in Venice for exploring the city - it's located exactly 100 meters from the San Stae vaporetto station, which I never needed to use because I walked everywhere.
Pros: 1) Great location. 2) Enormous size. The the space is exceptionally large as you get three floors all to yourself. 3) There is also a washer, which was a huge bonus. 4) There is good functional air conditioning in third floor bedroom. 5) Marcello is very kind, and outrageously fast to respond to messages. 6) Netflix - I didn't think I would use this, but you can't literally be exploring the city every second of every day. So this was a nice bonus during some needed downtime.
Con: the only negative I can think of is the stairs, which are very steep, a bit irregular, and have no hand railings. For example, the bedroom is on the third floor, but the bathroom is on bottom floor, which meant trips to the bathroom at night we're a bit of a trek. In the end though it's only a minor inconvenience.
Overall I enjoyed my stay in this apartment very much - it's quirky and memorable! Thanks Marcello.
