The apartment appears to be smaller than we thought. However it is really clean and host's cousin was very friendly. We had to check in at 3 pm, fortunately host allowed us to check in much earlier. The location is really good, it takes about 30 mins to walk to Colosseum and Baths of Caracalla, 10 mins to the nearest metro and train stations (by the way there is a train that goes from/to airport).
