I stayed for a month and was very happy with the apartment. It’s set in a quiet neighborhood only a 8 minute walk to the metro and a 20 minute walk to the Colosseum. The apartment was clean and comfortable and Flavio is a warm and excellent host who lives in the building and responds quickly to messages.
The apartment is small by American standards but cozy and perfectly fine for one or two people. I would gladly stay there again.
