We loved Marie's little heaven on the roof top! it was really cosy and we felt at home!
Marie is really easy to deal with and we had no problem arranging for the keys even though our plane landed close to midnight.
The area is really convenient! you will find nice little restaurants, supermarket, bakery, tube/bus station within few hundred metres. Also one of Stockholm "beaches is not far from the flat.
I'll be back in Stockholm and most probably in Marie's flat!
