This flat was absolutely perfect for our visit to Stockholm - it is extremely spacious, well heated for our visit in October, enormously stylish, and very, very comfortable. It is only 20 minutes pleasant walk to Gamla Stan and three minutes from the nearest train station. The beds are really comfy, the kitchen is well stocked with utensils, and despite being on a good sized road, is very quiet.
Marie was very helpful while we booked, and her friendly dad met us when we arrived and let us know how everything worked.
An amazing place to stay!
