My family loved our stay at Masemo’s apartment. The location could not be better. Lots of great restaurants nearby (one literally across the street), great neighborhood, easy access to hop on/off buses one block away, and 10 minute walk to both Trevi Fountain and the Spanish Steps.
For the kids (4 and 2 years old), the place was fun to explore. I didn’t really have to worry about them getting into anything, and they just generally liked the place. It’s quiet, and there is a pack and play in one room. Also, air conditioning units are in the two main bedrooms, the dining room, and kitchen.
In short: the place is legit and I would recommend, particularly for families.
