Giovanna's Place is a very good choice, the place is newly refurbished, well decorated and very functional, it has everything one might need for a short or a longer stay.
Location is perfect - on the main island, next to the lagoon, but in a quiet courtyard (not exposed to the see, but literally one step aside), at the quiet end of the lagoon promenade leading to San Marco - very practical if you are tired after whole day getting around the labyrinth of passages in the old city and just willing to get quickly home.
It is also 5 minutes walking distance from the Arsenal where the Biennales are hosted.
All shops and services - like grocery stores, pharmacies, bakeries are next door.
Giovanna herself is very kind, attentive and flexible person, it was pleasure meeting her!
Thank you!
