Manuel & Francesca were excellent hosts.
The location is great, if you intend to walk most of the time as we did. It was quite a long walk to attractions as the Colluseum and the Vatican City (about 25-30 minutes).
The apt. was pretty neat, only one thing worth noticing - the shower has a window to the hallway which is rugged glass in the middle but clear in the bottom and the top.
So it might be weird for 2 people that are not a couple.
Other than that - all was great, the communication and everything.
