I am sure there isn't a more centrally located place in Stockholm that is so nice and such good value for money. This is a very sweet apartment tucked up at the top of a building in the old town.
It's close to all the main sights of central Stockholm, not to mention there are two great gay bars downstairs which will meet all your schlager needs and then some. Despite the bars, we weren't bothered by any noise (we were there in the week so things may be different at the weekend).
Sofi clearly knows what she is doing with this place. Prompter check-in information would have been nice, but I received an instant reply when I asked, so no real problems there.
Highly recommended!
