The appartment was fantastic. In a safe area, close to a lot of sightseeing-spots (Vatican, Piazza de popolo, castel d´ angelo,...). We didn´t meet Lorenzo, but the communication was more than good: very reliable, friendly and informative! Lorenzo and Valentina sent us even the Information about the busshuttle from the Airport (not even a 10-minute-walk from the appartment and easy to find).
His mum managed perfectly everything with the room/the keys. The bathroom was small but nearly new, the room was spacious, bright and the whole place was very (!) clean. We definitely recommend that place and will book it again when coming back to rome.!
