Marcello's flat was in a great and central location, close to bus stops and walkable to many of Rome's tourist sites. The flat was clean and perfect for a couple nights stay.
Two issues:
Heating is via the A/C unit. My 1st night I couldn't get the heating to work and was very cold. I used the remote as one would for a A/C unit but the air come out very cold before I turned off the unit altogether as I was too cold and went to bed with my jacket over me. My 2nd night I tried again and discovered that after shivering for some time, the heat comes out after about 40 minutes. Had I known this I would've been better prepared the 1st night and been more patient.
Leaving, you must leave the keys in the lock box but you also need 1 of the keys or call the number you are sent- but there is no phone reception on the bottom floor so in a hurry (missed my bus), I had to leave bags below, run back upstairs where I had reception, call and then exit. A sweaty, extra step.
Otherwise a great stay.
