Andrea is a great host for his exceptional communication. (Thanks again for bringing the general standout to our attention).
In short, I can recommend Andrea's place for both atmosphere and location. It's close to some really nice restaurants and of course you can see the Colosseum if you lean out of the window. My son loved that. A Carrefour 24h Express Shop is also close by. We've felt home right away and enjoyed the stay very much.
The maisonette is located on the 4th floor of a well maintained apartment building. It is furnished part stylish, part somewhat old-fashioned, with a double bed upstairs and a third bed on the couch. The Kitchen provides equipment for basic cooking. The Bathroom is OK.
Tall people like me (1,94 m), please mind the low ceiling in some places.
Overall, thumbs up!
