Martina's B&B was perfact! The location is very close to the S.L station, it is about 5-7 min for a walk. And close to the vaporatto station that goes to the Burano. The room is very clean, warm and beautiful. Kitchen was vey useful. It has many of cook tools and some coffee. Bathroom is clean and beautiful, too. But, sometimes hot water doesn't work while showering.
Martina is very kind. She pick me up from a bridge that front of station. And, gave me many information about venice. It was very helpful.
The trip was very very happy. Thanks Martina! ^^
