The apartment was exactly as it was shown on the pictures! It was super comfy and cozy; we had everything we needed and it was situated in a calm neighbourhood. The subway station was at walking distance (10 minutes more or less) and there was even a grocery store nearby.
The only issue I found was that there were too many spiders in the house, but that's just my personal dislike (I am not fond of spiders at all) and it did not make the experience of staying at Dennis's home any worse.
If you are looking for a calm and cozy place to stay at while you are visiting Stockholm, this is the house!
