the apartment is large, well designed, centrally located - we enjoyed the location very much. Brando was very attentive, helped us with a lot of small things and was very timing - we liked him as a host very much!
We were able to find parking place just on the street 5 min walk from the house, that saved us a bit of money (as full two-days parking cost was only euro 16!)
The things you need to know - one bedroom faces the busy street, also you need to bring all the amenities with you:)
other than that this is a very good option to stay in central Rome for a family or a group of 3-4!
