Sabrina was a very friendly and professional host!
The apartment is located in a very nice, central, young, silent but generally crowded area. We could walk to the Colosseum easily and the next Metro station is close by.
Since it is an old building, we could hear the neighbours above us and in the staircase, but if you only stay there to sleep (which is the case if you are in Rome for a city trip like we did), it's the perfect apartment. The bunk bed is not very comfortable cause the mattress lays on concrete but the double bed was comfy.
All in all, we liked the apartment a lot!
