What a wonderful place to stay! The apartment is absolutely beautiful - the view from the windows is incredible. The hill and the steps were a bit of a workout for us (especially at the end of a day of sightseeing), but it was well worth it for the location.
Roberta is a great host. She and Paolo gave us a ton of recommendations for sights and restaurants. She even helped book us a taxi to the train station on our final day.
Highly recommended, and I can't wait to stay there again!
