Amazing location.
Easy to walk to Old Town and to the Slussen train station. Great restaurants, awesome neighbourhood and so convenient to get to anywhere in Stockholm.
The main issue we had with this apartment is that it wasn't really suitable for us for 4 adults.
Fourth person had to sleep on the sofa lounge wasn't comfortable and took up most of the living space. The windows also let a small draft through and this apartment, is right by the front door so a little noisy, although not too annoying.
Check in and out was extremely easy and convenient, and the host was extremely helpful. I would recommend apartment for maximum 3 adults who want to be in a good part of town.
