Marco is a great host. In this charming place which is small, Marco did a wonderful renovation and the space is optimally used.
The Location is great, close to San Giovanni and the Metro Station is in walking distance. There is an advantage, that you have a lot of shops and small local restaurants/bars around.
Just keep in mind, that when you are sensitive to noise, when there is a performance in the theater next to the appartment, that this could be disturbing.
