The apartment is super nice, cosy, and exactly like in the pictures. We loved the decoration, it is comfortable, and very well located to discover the city (2min from the Pantheon). We didn't see the host, but we got all information we needed, everything went very smoothly to get the keys and give them back. We had a taxi reserved to pick us up at the airport, which was very practical.
The only drawback of the apartment is that it is close to a bar/club and it can be very noisy at night.
