Myself and my 4 year old daughter stayed 3 nights here and really enjoyed it. The location is perfect (very near St. Mark's square and not far from the Rialto bridge) it was only a block away from Happy Pizza and one of the best gelato locations (which was a big plus for my 4 year old). The apartment is in a very old building (don't let the old looking stairs scare you) but the apartment itself is modern and immaculately clean. The shower was very nice and hot. The bed was a fold out from a couch but comfortable. The apartment was well stocked with nice big bath towels, plates, cups, glasses, pots/pans, toilet paper, paper towels, etc. and even had an espresso machine. The shower had shampoo and body wash (which I suspect were left by a previous guest so I would not count on being there). The only things that would be nice additions would be a small trash can in the bathroom and a box of tissues.
The apartment is perfect for 2 people, however, there was 4 chairs and lots of dishes/glasses so I was able to have family who was staying in another airbnb over for dinner one night. I also noticed there was some sort of baby bed or pack n play in one of the cabinets so it might be good for a couple with a small child (although there are some glass tables in the apartment that might not be good for a toddler).
Victoria was very easy to communicate and meeting up with her associate was very easy. We accidently broke one of the plates in the apartment while staying there and Victoria was gracious about it and did not ask for us to pay for a new plate.
One of my favorite parts of the apartment is that it is near (or possibly connected to) an old Armenian church and on Sunday morning you could hear the singing (but not enough to wake you up). You could also hear church bells from St. Mark's square at 6:30 every evening.
If you are a couple looking for a great apartment, in a great location, at a good price, I would recommend booking this apartment.
