Everything was great with this place. It is in a really good location, close to the sites and near some excellent cafes. The place was really clean, Gian Marco is super friendly and helpful. The bed is comfortable and the studio flat is spacious with everything you need for a short stay.
The only slight drawback was that there was some machinery (could be the lift or a hot water system) that makes quite a loud, intermittent grinding sound which doesn't bother you once you are used to it but might keep you awake a bit to start off with. Bring ear plugs if you have them. Other than this noise, everything else is really quiet.
Despite the mechanical noise, it is a great place in a great location with a great host.
