This location cannot be beat! It is a close, easy walk to the Vatican, restaurants, and the metro. The room itself was clean and smelled wonderful as we walked in. The space is very pretty, and perfect for a group of 4 or 5. Convenient little kitchenette, 2 large comfortable bedrooms, a sitting room (with a sofa that can sleep the 5th person), and a very nice bathroom.
We did not meet Stefano, but he was very quick and courteous with each of his email exchanges. We did meet his sister, who let us in, gave us a tour, suggestions on where to eat, and was very hospitable.
The only things guests should keep in mind that we did not realize before arriving are: if you happen to be driving to the location, it is best to have a GPS! We had a map that was not so great and the many one way roads around the apartment frustrated us while driving in circles trying to get on the right road. Additionally, while there is parking provided as part of the apartment, it is not a dedicated spot, and there was not always a spot available. Lastly, do not forget that the resort/rooming tax is due when you arrive. Luckily Stefano's sister was nice enough to direct us to the nearest ATM.
We loved our stay in this apartment, and plan on using it if available the next time we visit Rome. Location, size of apartment, price, and cleanliness cannot be beat! Having wifi was great, and we felt safe and secure staying in the neighborhood and apartment.
