Rosy's apartment is spectacular! Very cute apartment with a great view, convenient location, everything you need for a comfortable stay and its in a very quiet building. You can walk every where within 10 minutes and there are coffee shops on the corner and neighborhood stores a block down if you want something closer.
Rosy met us at the apartment and was very helpful giving us historical information while explaining the map. She also booked us a taxi the morning of our departure which was a huge help! My friends and I LOVED this apartment and I strongly recommend staying at Casa Colonna. Hopefully I will have the opportunity to stay there again in the future.
