We arrived much later than expected due to flight issues, so Carlo, the apartment owner, met us. He couldn't have more lovely. Gave us some great tips for Rome, helped us fight off a scary taxi driver (long story) and stayed in touch via WhatsApp if we needed anything. 5 out of 5.
The apartment is in a perfect location. About 10mins from everything you want to see in north Rome and 20 from everything near the Colosseum. Small but has everything you need. The bed is SO comfortable which is a highlight after a day of walking and exploring.
