Laura is very easy to reach if needed, she answered all our messages very quickly. Check-in was easy, with Andrea. Don't forget you need to pay the tourist tax on the spot as per the ad (expand the description).
The appartment is in a great location, very quiet environment with the windows giving on one of a small canals of Venice. Located between Rialto and place San Marco, it was a pleasure to be within a walking distance from so many shops and sites.
Definetely recommended!
PS - we had no issues with WIFI or surrounding noises. (to compare with previous comments we've seen)
