The apartment is about a 15 minute walk from the Rome Termini railway station. We found the place with no problems. Amen was easy to contact. She left a phone for us to use to contact her. (We didn't need to.) It is a bit away from the tourist areas, which is good as the area has a more authentic Roman feel, but it means that getting to the tourist areas takes a bit of planning. There are busses close by, but we tended walk and catch the metro. There are lots of good eating places in the vicinity.
The unit is clean and modern. Two large bedrooms (one double and one twin), a modern washing machine and cooking facilities. The living area outside of the bedrooms is very small, situated in the cooking area. The apartment is on the first floor and there's no lift. Several flights of stairs to climb with luggage.
To summarise, a nice apartment that met our needs.
