Massimo is great! The location is perfect, just beside Termini and has quick access to all the destinations that you'd like to see in Rome. The place is clean, neat and convenient. There are about 3 or 4 rooms in total, including Massimo's accommodation and is normally full of young people eager to explore the city the same way as you. Massimo offered some very helpful tips regarding the touristic destinations and some insight on the food, nightlife etc. We didn't have A/C in the room but even though it was sizzling hot during the day, the nights were chilly and we did not have issues with the lack of air conditioning. Lastly, I lost the keys for the apartment during our visit in the Vatican, however, Massimo was cool about it and only asked us to give him some very small and reasonable amount of compensation for the inconvenience. Overall, it was great staying there and I would recommend it for a short stay in Rome.
