We just came back from almost a week at this lovely apartment. One of the best things about it is probably the location - it's walking distance from anywhere you'd want to go in Rome and is surrounded by cute boutiques and local bars.
The first two days of our stay there was a problem and the apartment had no hot water. Daniel and his mother did everything to help fix it as quickly as possible and we also got a full refund for those days, which was very appreciated. The apartment is a bit dark as it doesn’t have much natural light due to a lack of windows, but it isn't much of a deal. It's well furnished and has anything you could need during your stay.
The apartment is a great value for your money, we would definitely recommend staying here.
