We had a great stay. The penthouse is very nice, and very well equipped (cable tv, two flat screen TVs,). The outside deck is fantastic, great view and sunny. Roberto is a good host, during our stay he replied to all our questions very fast.
The bedroom is facing the street where there is a tram line. Light sleepers may be bothered by the noise. We were not.
I highly recommend this Airbnb and would not hesitate to come back.
