We stayed for 2 months. Andreas was very responsive and friendly when we needed something. The apartment is quite big and spacious. Bedroom, living room and kitchen, all good.
The neighbourhood was very quite. Not many things to do around but you are 8 mins walking to the green line metro station and from there 20 mins to go the very center of Stockholm. You have 1 supermarket next to the metro station and bigger ones 10 mins walking distance (from the apartment).
The only negative point I can mention is the bathroom. The apartment is on the first floor and there was almost a constant smell from the sewers. It seems to be a building issue so there was not much that Andreas could do about it. Staying for short periods it's not something i'd worry about, but after 2 months was a "pain point" for us.
All in all, it was a good choice for us. It would have been perfect if there was not the issue with the bathroom.
