I had a wonderful stay in Venice!
Agostino is a great host. The place is cozy, clean, for Venetian standards very spacious and has a beautiful large balcony. The flat is located in a nice neighborhood and within walking distance to Piazza St. Marco and the main locations of the Biennale di Venezia (Arsenale + The Giardini).
I would recommend the apartment to everyone!
Thanks a lot to Agostino.
