First, I would like to mention that Federica and Francesca were both very kind, responsive and helpful. Very much appreciated!
In terms of the apartment, it is wonderful really, a sweet place and cozy. Value for money in my opinion.
A few MINOR things I think worth mentioning:
1- thin walls indeed (other comments mentioned it) of the apartment, makes all sounds at the building to be heard in the apartment. If your sleeping is very sensitive to noise, I wouldn’t recommend
2- water stream in the shower slower and smaller than I would prefer.
3- location-wise, it’s super close to the coliseum, and walking distance from many places. But note that it’s not what people would call the heart of Rome.
