We had a wonderful stay at this apartment. It's comfortably furnished with a well-outfitted kitchen, spacious bathroom, good-quality beds, and very fast internet. The hosts met us at the apartment and made us feel right at home, inviting us to make use of cooking essentials, beach toys, and their extensive DVD collection. The balcony was a lovely extra for a June visit, and our kids loved the playground at the foot of the building. Geographically, it's ideally situated: the local neighbourhood has lots of interesting shops, restaurants, and cafes, you can walk (~25 mins) to Gamla Stan, and you are less than 5 minutes from Stockholm södra station (commuter rail) if you want to go further afield.
We would certainly stay here again on any future trips to Stockholm!
