This flat is in a perfect location and is large and well equipped in a beautiful old building. It had the best shower or our 6 air bnbs. The flat is the top floor of the building and there is no air conditioning, but the fans they provided worked well with open windows to cool it off. Be prepared for a nice climb each time though-there are a lot of stairs and no elevator.
The host company is responsive and pleasant. Our only difficulty was the check-in where we told to find a key in a lockbox outside the building and it turned out that we just needed to enter a code. After that everything was great. If they fix the check-in process I can highly recommend staying here.
