Robin, who acts as the owner's agent, was very helpful and friendly. She met us as planned, and didn't mind our last minute change of arrival time. The apartment is on the top floor of an old building on the grand canal. It is 91 steps up. It can get very hot and the air conditioning unit is essential and only partially effective. Beware very hot weather. The place had the feel of student digs but is surprisingly pleasant to stay in.
The location by San Marcuola waterbus station is ideal. A quiet area apart from the neighbouring pianist who plays complex pieces at all hours.
