William’s place is super central in the very pictoresque Gamla Stan. However, the apartment was smaller than expected and the number of private rooms and their accessibility make the place not suitable for groups with many couples or older people. I was there with my family including seniors, and there were quite a few steep / crooked stairways to access all but one bedroom. I suppose this is the charm of the old house. Otherwise I would certainly recommend the place, very cozy and stylish.
