Martina's flat is very well located in Venice, it's next to a small piazza that's bordered by a few nice places where you can have breakfast/ dinner and really close to Rialto Bridge. It's also very convenient whether you arrive in Venice via bus or train, approx. 15min from either of the stations.
When we arrived we met Olimpia, Martina's sister who was very nice and helpful and gave us a few suggestions for restaurants and places to see.
I gladly recommend the flat and would stay here again.
