The place is nice and the location is amazing. It has a very cute balcony that overlooks the narrow street.
A few things that were not convenient are the bed in the main bedroom (at least) was spring bed so not super comfortable, only one toilet paper per stay and to get into the building was a pain. We opted to not get a key and we used the app. If you have great reception it should go pretty quick but if you are like us, you might spend a good 5 min every time you enter the building.
I would stay here again for the location but I would def get a key.
