My sister and I were met at the waterbus stop at the Rialto and shown to the apartment, which was five minutes walk away. Everything was explained to us on arrival, and the apartment was located between the Rialto and San Marco. It was perfect for our needs, beautifully clean with a good shower. and plenty of room for two people. I would be very happy to use this apartment again.
The only drawback was that it was on the second floor and had no lift, so arriving and departing with luggage was a little difficult.
