We enjoyed the apartment very much.

1. Location, location, location! In a quiet side street but very central to everything, about 5 minutes walk to San Marco and Rialto, very short walk to S. Angelo via small streets lined with stores. Apartment is not noisy at nights, it's away from the crowds. Could not the better situated.
2. Hosts: Alfonso is very responsive and Nicolette is lovely and very helpful.
3. Amenities: fully equipped kitchen is definitely a plus, we didn't cook but everything you would need was there. Nice apartment, pretty decorations. There is no elevator, but there is a small private space downstairs where we could leave the stroller to avoid carrying it up and down the steps. Washer and dryer machine worked just fine, which helps when traveling with small kids.
4. Temperature: apartment was a bit cold when we first checked in and warmed up overnight when we turned up the heat. Closing the shutters helped too, but aside from being a little chilly on arrival, the apartment was very warm and cozy for the rest of our stay.

Giving it just 4 starts because of the lack of small things, i.e. attention to details such as providing some extra cozy blankets and pillows, better wiping bathroom mirror, etc. that would really make it a 5-star property.

Thank you for making our stay in Venice very pleasant.
