The apartment is nice, in a perfect position for visiting Stockholm and the street is the same of Mikael Blomkvist's apartment (for Millennium fans!).
The host is very precise with communications so the self check-in and check-out were flawless.
The bed is not a full double bed so sleeping there in two can become uncomfortable. Also, for some reason there were two duvets neither of which was big enough to cover both of us so we had to use both of them, again not very comfortable.
Contrary to what stated in the description there is a nice smart TV which is a very appreciated addition to the room. However, the "best effort" WiFi is a joke: it keeps disconnecting every few minutes and even when working the speed tests were around 1Mb/s download and upload, which is not enough to stream video content so I had to rely on the internet connection of my phone, quite inconveniently.
The bathroom is a shower with a toilet and sink in it. Not the best but it was clean and you get used to it fast.
Overall not a bad accommodation, but a real double bed and WiFi would take the stress out of the experience.
Didn't use the kitchen
