This modern apartment in a beautiful old (1600's!) building was a wonderful home base for our 5-day visit to Stockholm! Access to the apartment is up a circular staircase of (~60!) lovely, hand carved, stone steps; it really set the stage for our visit, but note this if mobility is an issue for you. The bedroom had ample storage and hangers; the kitchen had all the basics (coffee maker, kettle, dishwasher, large refrigerator/freezer and plenty of dishes/pots/knives, etc.); and the open living/dining area was relaxing after a long day of exploring. The bathroom had limited storage, but included a small washer and dryer, which were appreciated given that Stockholm was just one of our stops in a longer trip. Good wi-fi also! The location of this apartment can't be beat! Gamla Stan is a lovely historic area of cobblestoned streets, truly amazing restaurants, and lovely shops. Plan to spend an ENTIRE DAY just walking each street; we wish we had, as there was always something new to discover even if shopping isn't your interest. Two small grocery stores are nearby. We were visiting in late October, so noise and crowds were not issues, but I could imagine these might be something to consider in peak season when the windows are open. All in all, I would highly recommend this apartment for a stay in Gamla Stan, and hope to return in the future.
Suggestion: If you are arriving at Gamla Stan station with wheeled luggage, the cobblestoned streets can make the walk slow and loud. You may want to walk around the edge of the district and take Skeppsbron to the alley (Stora Hoparegrand) that runs along the apartment's building, which only adds about 5 minutes to the walk.
