Trevi’s place is actually very beautiful. It is a shame that when we went to stay with him, he did not provide us with the proper keys and we were forced to contact him each time we were trying to enter and exit his place. This will not be a problem for you if you have a SIM card that can call Italian numbers. Also, the air conditioning did not properly work and it was impossible to catch any sleep during the hot summer nights in Rome. Location is very good and you are a walkable distance from the Colosseum.
