If it's available, take it!
Fabrizio is a very hospitable and punctual host. He is also very busy outside of the upkeep of the quarters, so the guests should have that in mind when scheduling departure.
The place is located 5 minutes walk from M5 metro line, which leads directly to most of the tourist attractions. Only 5 minutes walk further is a supermarket.
The bed is very comfortable and the balcony is a wonderful place to have breakfast. There is an interesting choice of books available. Fabrizio seems to be a fan of modern art and surrealism which shows in the decoration and was an appealing touch.
Overall the stay is very comfortable and pleasant as well as unbelieveably affordable for this standard.
