I thoroughly enjoyed my stay in Roberta and Paolo's apartment. The location (close to water taxi station and nestled among luxury shops) was convenient and made me feel safe. It was easy to visit San Marco square and walk to nearby neighborhoods for great food + drink.
These are also exceptional hosts- from providing accurate travel and transportation info; to having numerous amenities for visitors in the apartment; to being available for any and all questions.
I would highly recommend anyone visiting alone or as a couple to stay there.
