This location is (by walking) about 10 minutes from the Termini Station and about 15 minutes from the Rialto Bridge. The location is close to a supermarket and lacks the crowds of the more touristy spots (as it is more in the middle of the top part of Venice). The apartment matches the description pretty accurately and the furniture is pretty comfortable. The only thing to note is that this location does not have Wifi (however, wifi is available in many restaurants in Venice) and the lack of Wifi does not decrease how nice this location is.
The host was quick to respond and provides more detailed directions to the location. Check-in and Check-out was easy. Overall this place is a great deal in a good location (away from the tourists). I would recommend this place for a short-term or long-term stay in Venice.
