The owner was really nice, available and gave us many advices about things to do and to see.
The apartment was very well situated (Coloseo area) in a quiet and typical place.
The Metro was pretty close (10 minutes walk)
The apartment is well decorated, very romantic, exactly the same shown on pictures.
It's really for 2 people not more cause it's small, a bit disapointed with the bathroom (very small and not well functional), the other point is that it's not very bright cause the window was facing a wall and it was not possible to open it fully so it was quiet stuffy. (Clostrophobe refrain!)
