We spent five nights at Maria Teresa's place and only have positive feedback to share. The apartment is conveniently located 5 minutes away from Colosseo and Colosseo subway station. A small supermarket is around the neighborhood, and the whole area is very quiet.
The apartment offers everything needed for a great and peaceful stay, including bed linen, towels, kitchen facilities, and even some great coffee, etc... Maria Teresa is very responsive before and throughout the stay. She would typically reply within an hour of time and we very much appreciated her care. We would recommend anyone to stay at that place for a happy and affordable stay while in Rome.
