This is a agency-managed apartment, which comes with the caveats of being managed for economic efficiency (more below). Raffaele was there on time to check-in and I had nothing specific to report beyond the noise level being quite high despite being located a bit off the main streets in Monti. The neighborhood is absolutely amazing and the apartment is close to metro Cavour (5' walking). The rooftop deck is definitely a plus.
PS: Beyond the price that gets computed by AirBnB, expect in the fine prints many additional costs such as linens, fee for late or weekend check-in, etc. In a sense, it allows more flexibility to adapt fees to the profile of customers, but the increased prevalence of such practices risks making price comparisons basically useless.
