We really enjoyed starting at Janusz's place. Janusz was very hospitable and provided helpful tips on navigating Stockholm.
The apartment is located in a nice residential area just a short metro ride away from most points of interest. The airport buses stop very close by so getting to the apartment from Arlanda was a breeze. Despite being residential, the neighborhood is quite lively, and you can always cross the bridge to Hornstull where a lot is happening.
Having a balcony during the summertime is also a great perk, as is having a friendly dog to play with. We will definitely stay here again on our next trip to Stockholm.
