Maurizia and her husband were wonderful hosts. They were warm, accommodating, and very helpful. The apartment is 2 floors. There is a beautiful entry way that leads to a lower level kitchen and the bathroom. Upstairs are the 2 bedrooms. The apartment is located on an out of the way, less traveled but very close to everything campo. I was there with my 2 teenagers (17 and 16) and it was perfect for our needs. The beds were all singles, but very comfortable. It is a Venitian apartment that feels like a place you would be renting if you were living in Venice, not a hotel.
My one and only caveat is that if it is going to be very hot while your are visiting, realize that there is no air conditioning. With the windows open, the apartment does cool down well though. I would definitely stay here again and miss it already.
