My wife and I stayed in the apartment for a month. The apartment is great, very comfortable, stylish, comfortable bed, and is well equipped with everything you need. The internet is fast and stable (80/30mbps). The apartment is in Santo Spirito near the basilica. There is a daily farmers market in the square and it is close to several great restaurants, bars, and the best gelato in town (Sbrino!). We would definitely stay here again.
Note: you are required to climb stairs to the apartment but not too many so don’t be dissuaded.
