This is an excellent place to stay, especially if you are going to the east side of the city. I was attending a conference at the university, and the location was perfect for walking there, but also good for general sightseeing with bus and metro lines not too far away. The district itself is great, lots of cheap good eateries and a relaxed neighbourhood vibe away from big streets and shops. I wouldn't recommend walking alone from the Termini station to the apartment very late at night, but I felt perfectly safe walking around the immediate area at all times. Carmen is a wonderful host, very helpful and friendly but not at all intrusive. She keeps the place absolutely immaculate, cleaning every day and changing beds/towels frequently. I stayed in the red room which I found spacious and delightful. The bed was super comfortable and there is also a very useful desk, a daybed/sofa and ample clothes hanging/storage space. I also really appreciated the aircon in my room as it was a very hot week even by normal Roman summer standards. There are very thoughtful touches throughout, including supplying separate bath mats for each room to use in the main bathroom. The place works well for longer stays as well as being great for overnights or weekends, (I was there six nights), with a washing machine available for 3 euros a wash. The apartment would also work well for a family or group of friends as there are two bedrooms rented out with multiple beds in each, and two bathrooms -- if you can find a time when both rooms are available. Do note, there is no cooking allowed, although basic breakfast (cereals) and good coffee are included in the room price, and a more substantial breakfast can be arranged with Carmen for 5 euros. Overall, highly recommended.
