This place is amazing. I stayed here with two friends and the space was absolutely perfect for us - double bed and bathroom each.
The location is incredible, right on the castel peninsula among the cute bars and restaurants. Beware, you will get caught up in the atmosphere on the way home each evening - we never once made it back without being lured in for a delicious nightcap first.
Marcello was a superb host - he sent some really good and detailed instructions ahead of our stay, gave recommendations and directions for some of the spots we wanted to visit, and checked in halfway through to make sure we were all ok.
We will definitely be back here, thank you Marcello!
