We spent a very pleasant three nights in Carlotta's apartment.
Reception was very smooth, and both checkin and checkout times were very flexible.
The apartment is very cosy and feels like a "real" home. There are views from the multiple windows onto Bologna's old center as well as the surrounding hills. The apartment building is very historic and has beautiful staircase. Beautiful! The only thing to keep in mind when booking is the large number of flights that must be climbed to reach the top-floor apartment.
The apartment is in a good location. It is situated just outside the historic center. The street outside can be busy at times, but this is basically not a problem because all windows face the back. We did not hear any noise at night. There are several nice restaurants as well as very "local" bars within walking (5 min) distance. There is also a bus stop 2 minutes walking away which connects directly to the railway station.
All in all, we couldn't be happier that we chose to stay here!
