Awesome experience there.
The apartment is very comfortable and cosy, very well equipped. Only 10 min on foot to San Marco Plazza, but all the streets around are also very bustling (it's Venice).
We were very well received by Mr. Diego who explained everything and made sure that everything was perfect. We only had one small letdown regarding the washing machine: it was unusable because it made the fuses of the apartment blow.
Matteo was accomodating and let us stay in the apartement a few hours more before our flight. Always very convenient.

Thanks a lot Matteo (and Diego).
