I highly recommend staying in Gamla Stan if you visit Stockholm. The old neighborhood is wonderful, and Tom’s flat is also on the edge so you get the best of both worlds in being next to the waterfront and connections to other parts of the city. The flat is spacious and clean, with coffee and tea provided, such a nice touch. There is a Murphy bed in the front room if you have extra guests. My college age daughter stayed there, but it was noisy with old windows and an active restaurant on the street. But she’s in a dorm so it doesn’t bother her. The bedroom was quiet, although Tom provides ear plugs for those less tolerant. Keep in mind it’s an old building so be prepared to carry your luggage up two flights of stairs.
This has been one of my favorite Airbnb properties I’ve stayed and I highly recommend.
