My mother and I stayed in Frédéric's apartment on our recent week long trip to Rome. Frédéric was a communicative and warm host. He welcomed us personally and really went the extra mile to make sure we enjoyed our stay, including providing tips about local places to eat and his suggestions for things to see and places to go in Rome beyond the few big ticket stops that everyone makes. He was proactive in sharing information with us during the stay related to some street work being done nearby and also responsive to a few questions I had. I always appreciated his quick and clear responses.
The apartment is charming and met our needs and expectations. It is cozy, feels homey, and is decorated well. The second bedroom was actually a bit bigger than we anticipated based on the pictures. We had already been traveling for awhile when we arrived and were very relieved to see the in-unit washing machine. It was a nice bonus to have coffee and a few other breakfast items available as well. We only needed to use the AC one day, but it worked well and kept us cool. In general, the apartment could use a little a little refreshing/updating, but overall we felt right at home.
It has to be said that the location cannot be beat. We LOVED staying in Monti. Frédéric's apartment is set back enough that it is quiet at night but easily accessible to the great shopping and dining in the neighborhood (as well as the Coliseum of course, which is just a few blocks away). I highly recommend staying here and would be happy to visit again.
