The appartment is located in a nice neighbourhood a few minutes away from Campo dei fiori. You can find some nice places for breakfast or dinner around. It is quite central orientated to walk to the center, the Vatican or the Colosseum.
The appartment itself is very charming. It is an old building where they installed a new bathroom and kitchen. Bathroom is quite large comparing to other places I visited on Airbnb. As it is an old building there are some minor issues as well : noise from neighbours can be heared at night. and the tiles of the floor are lose. You can hear them / feel it as you walk.
For us, the biggest inconvenience was the bed. A bad bed / matrass causes me backpain. I'm quite sensible about this. It is a personal issue but in my opinion, it can use some change. We managed to help ourselves by putting the bed cover above the mattress.
If they deal with that, i would rate it a 4.5. Now I've put a 4.0 on it. I can recommand it and i would consider to stay there again if i go back to Rome in the future !
