Pina's apartment was perfect for us. We were in Rome to run the Maratona di Roma, and we need a place near the finish line, which was at the Colesseo. The apartment is just a short walk from it. You can also walk to all other attractions, such as Trevi, Spagna, Navona, etc., but if you prefer to take a bus, there is a very convenient bus stop two minutes from the apartment.
The building is beautiful, very traditional. You really "feel" in Italy. The bed is very comfortable, the shower is great, and the kitchen has just about everything you may need for a quick meal (I didn't do more than that). The apartment was very clean and exact as described and shown on Air BnB. If I came back to run next year, I would stay here again.
