We were firstly very impressed that everything in the hotel look so clean and new. It was not too far from Kista t-bana (metro) and be sure to ask the host if you want to know the shortest route possible to the metro station or Gallerian. I'm so glad i asked the first day! Booking through airbnb is cheaper than the hotel website but it comes with some limitation as well (room cleaning limited to once a week). Laundry is limited to once a week also but that is probably across the board. There is a bus terminal at the other end of the metro station where the bus terminal is located and the airport bus stops there. So so convenient (20-30min from Arlanda).
The studio room that we rented is very cosy and has all the basic amenities, it really felt like home. The flooring in the room is wooden, so it is not so cold even tho it is winter and it is perfect with toddlers as it is easy to clean (compared to carpeted flooring) and won't hurt if they fall (we have 3 toddlers in this trip).
We would definitely consider this hotel when we are visiting Stockholm again and will highly recommend it to anyone visiting Stockholm.
