The apartment is in a good neighborhood. The room itself is pointing to the Main Street and is even a little bigger than the photos suggest. The Main Street is not really quiet though.
Maria has good hints for you regarding the neighborhood. She is helpful and nearly always at home. There was a second guest in the apartment during my stay (2,5 months). Basically, the room is a good choice, I had some unexpected issues though when it came to receiving friends that wanted to visit me. Maria usually does not want this and I had to pay extra or in the end booked another apartment in town.
