We really enjoyed our stay at Antonella's! We didn't get to meet her, but in all her communication she was very clear, easy going and welcoming. We had an early check-in to match our arrival time and could leave our bags after checkout, which was very convenient. The breakfast was really nice, to be eaten right in our own room. The room itself is stylish, with nice colours. We didn't have any problems with sharing the bathroom with another room. The location of Dorsoduro is nice and quiet, although you do have to walk quite a lot to get to the main attractions. This feels normal in Venice though. All in all, we would definitely recommend this place!
