Aura has a very nice place with a great location on Gamla Stan. A few minutes to the royal palace and in the heart of the main tourist area, yet very quiet and safe. It's 4 minutes to the Gamla Stan T-bana. I timed it and I even made it to Centralstation in a total of 7 minutes because I caught a train right away. There are 5 lines running to Centralstation so you won't have to wait long at all.
The apartment is one very large room with a nice kitchen included and also has a nice bathroom. The bathroom has a nice walk in shower and the shower curtain is effective and keeps water off the bathroom floor unlike some other places I have stayed in. The hot water is strong and comes on immediately . You'll enjoy your shower.
The bed is comfortable and there are good shades to darken the room although since I like absolute dark, I used my night mask too. The hot water heating system was good and easy to use. You have to turn on each of three radiators or perhaps less if your want. I highly recommend Aura's place.
