The experience in Martin's house has been great! We found the house in very nice conditions, it is located very near to the city center (Gamla Stan), only 10 minutes walking and 1 metro station, and also very close to the places for going out at night. The area is full of restaurants, and there are also a couple of supermarkets nearby. He has also been very helpful and kind with us.
In general it has been a very good experience and I would certainly recommend Martin's Flat.
