My sister and I booked this apartment months ago. We had fantastic communication with with the host all the way up until the first day of arrival. We were late with our appointment to get the keys, but our host waited for us until we arrived. The host was extremely friendly and helpful.
The apartment itself is wonderful. You most likely won't find anything as uniquely decorated and laid out anywhere else in Rome. It is in a great location, only 2 blocks to the Coliseum, and a two minute walk to the nearest metro station. The street that is on is lively, but it is one of the reasons to visit Rome. My sister and I walked a total of 50 miles in the week so getting a good night's rest was never an issue.
I would easily recommend this apartment! Next time I'm in Rome, it will be the first apartment I look up to see if it's available.
