The flat is as advertised, clean, fully furnished, each room is of a good size, and the bathroom is quite big which is pleasant. It's really comfortable for 2.
The flat is really well located, close to the pedestrian street where you have everything and can enjoy nice dinner, apé, drinks, ... (Primo al pigneto, Pigneto 41 enoteca, ...), but also really quiet once you are in as you don't hear the noise of the Pigneto street.
There was a small damp smell in the living room but was absolutely not an issue. There was no smell in the bedroom and bathroom as you can let the windows open.
It is easy to reach the city center with the different bus or trams that are close to the flat: central station (15 min) or Coliseum (20 / 30 min).
Mario has been a great host preparing our arrival, meeting us at the bus station and giving explanations on how to move to the city center. It is also pleasant not being rushed for leaving the flat or giving back the keys.
