We had a great stay at Betty's. Perfect location right next to the Duomo and walking distance to restaurants. The flat had everything we needed, kitchen was well equipped - we cooked a couple of times with no problems. Also very quick responses and easy check in. Just be aware there is no air con - but instead there are 2 fans, and the flat is on the 4th floor so be prepared to walk a bit! Overall I definitely would recommend to others.
