Excellent!! If you are in Rome you should stay here. My wife and I were here for a 4 day stay and loved it. There are a lot of stairs but worth it. We stayed in three other places while in Europe and this was by far the biggest. Paolo was hospitable with providing fruits and milk. We never meet Paolo but we were taken care of by someone who worked for him.
The location is amazing, you are 2-5 minute walk to the forum and the Colosseum is close as well. There is a bus stop 2-5 minute walk away and also a metro stop 5 minute walk. If you are looking for a central spot in rome but also want to be near the local areas then this is your place. There is a small square 2 minutes away where there are about a hundred locals hanging out every night around a fountain. Great environment and experience of life in Rome.
Paolo has everything you need in this place as well. Everything form an iron, full kitchen, to washer machine.
Rating this place four stars because there was not a shower curtain which made showers a bit stressful because we would get water everywhere in the bathroom. I was on vacation, I did not want to worry about anything. If this did not happen then it would be 5 stars.

Thank you Paolo for the great stay!
