The apartment is really beautiful and nice, comfortable, two steps always of the Colliseum and of the public transport, the area is quiet, calm, and secure, we will probably stay there again!
The only problem that we had was with the showers, the weather was or too hot or too cold, there's not a middle term; also you have to read about the tax fee! This is kinda and Hotel so they will charge you with 3 euros per night!
Anyway, I can say is highly recommended!
