It's a nice apartment with enough beds for 3-4 people. The air conditioning is amazing and I miss it already. We had everything we needed. It was very clean. Unfortunately the street is very loud, but it's very close to the vatican and a bus station into the center is right in front of the house. I can also imagine that every street in Rome is very loud.
We were really satisfied with our stay and the apartment was a great place to relax between all the walking in the city.
