The apartment is situated 15 min walking from Coloseum and Termini station (different directions) and near metro station, it is very comfortable. Gaia is very communicative person, she gave us useful recommendations how to find the apartment and met us near the house and gave info about shops/cafes/sights and so on. But she asked to sign the contract.
The apartment isn't very modern but clean. The bed is on the second floor but the ceiling is very low and first night I hit the head.
Generally everything is ok!
