Elena's place is great because either Elena or her husband meet you at the train station and take you directly to the unit. This is very helpful in the confusing city of Venice. They also explain to you how to use the 5 main neighborhoods in Venice to navigate the city. They basically explained how you can never be lost if you just follow signs to your neighborhood. This helped us relax and very much enjoy walking around the City.
Elena's place feels very safe and homely because it is in a building with only two units. Your unit and Elena's.
Elena and her husband are readily available. The wifi broke down while we were there and we messaged Elena during dinner and she had it fixed by the time we returned from dinner. Very impressive.
