First of, let me say that we were allowed to leave our luggage a little longer in the apartment. This was very helpful because we did not have to worry about finding a locker for the remaining hours in Rome.
Regarding the apartment itself let me emphasize that we totally loved its location -- absolutely fabulous; pretty much all the sights are in walking distance, and several of the guided tours we took ended rather close to the apartment.
The host was very helpful, friendly, and always easy to reach. The checkin was easy and went smoothly.
The apartment was very clean and spacious (for two persons and compared to a hotel room). The interior is a little bit old, but you can clearly see that on the pictures, so this is absolutely okay.
We believe that given the location the price is very fair for what you get.
All in all, we enjoyed our stay and can definitely recommend the apartment.
