The location it’s not super good (its like 20’ by metro to gamla stan, or 50min walking) so it’s something to take into account depending on how much time do you spend on the city. If it’s several days it’s worth it for the price this apartment, but if it’s one/two nights definitely i would try to check something closer so you don’t spend that much time on the way.
About the apartment, one thing that was very disappointing is that the door of the room was not fully opaque but translucent. So as they are other people living there I woke up like at 6am due to the light that got through the door. Also, there was no paper bin in the room or kitchen.
Apparent from that, the room was clean and the bathroom too which is very important.
The communication was very good with the host. Its a bit tricky to get there but if you follow the instructions should be fine.
