Excellent location, near Saint Marco square and Duomo and water taxis and walkable to all the main sites. A small balcony in livingroom with a view of the canal allowing us to see the gondolas passing by while having our morning coffee.
The historical building is renovated with access by water taxi. Our host arranged a private water taxi for our group directly from the airport.
AC kept the appt cool; however, one kept making noise all night long the first night. I adjusted up the temperature to 25C, the noise stopped - it was so hot outside, 25C inside was OK to us.
Kitchen is well equipped. Our host is quick to respond to our text, checking in and out was easy.
We had no problem going up the stairs to the 3rd floor (no elevator).
Washer is small and older about 12" deep, just enough for a wash of basic laundry for our group of 6. Making sure asking for the manual if not familiar European/Italian model.
