A lot to like about this rental, though it falls just short of 5 stars. Great location - quick walk to many historical sites, and yet on a quiet street, with little traffic and few pedestrians. A government building next door means there's a frequent police presence close to the entrance. The host's agent who meets you is extremely friendly and helpful, and provided separate 4 sets of keys. He was there waiting to let us in and responded quickly to issues that arose.
The apartment is a good size, with high ceilings, large windows, and lots of light. The major drawback is the terrible quality of the beds. The cheap bedding and the living room furniture isnt much better. The hot water on demand system does not hold constant temperature for showering. The elevator is primitive, even by Roman standards, stopping only at half floors. The building collects trash in the entrance lobby.
So overall: nice apartment in a nice location, rented by nice people - just needs some investment.
