It´s a great apartment and Maryana is a great host.
The other reviews don´t give a clear idea of the location of the apartment and if you try in google maps you might get a wrong impression. The fact is that the apartment is in a perfect spot. A very residential neighborhood with easy access to bus stops and subway stations. The area is very safe to walk even at night.
the train station is nearby, but there is absolutely no noise.
Eataly is around 6 minutes’ walk, and there are many options of bars and restaurants at via Ostiensi.
