We stayed here over Christmas with our family of six and really loved the space. The beds are very comfortable with nice linens that really allow for a great night sleep. Everything is very modern and updated in the apartment and absolutely spotless. Nicola went above and beyond by having groceries ready for us because most shops were closed on Christmas Day. We also had miscommunication as to when we would arrive (on our part) and he let us in early with no problem.
Nicola is very quick to respond and easy to work with!
The location of the apartment is close to the Termini which has a really nice market, shops, and is great if you're doing day trips or going to other locations. However, we were told the area close to the train station is not the best- especially at night. We had no issues with safety, but if we did it again we would make sure to be inside of "Ancient Rome" instead of outside the city walls. However, you really can't beat it for the price.
For us- it was hard to find 3 bedrooms with big beds and 2 baths so this worked out very nicely overall!
