The apartment is really cosy, the terrace upstairs is a must, the kitchen is absolutely fully equipped with things a cook like me would never imagine to find in a place for rent. Wonderfully clean, perfect contact with the owners. The location is more than great! We were three friends, we each had a bed (two bedrooms and a sofa bed).
The two “cons” : 4th flour , you have to walk up with the suitcase (the owner warns you about it, so not a surprise… and nearly every flat in Gamla Stan has the same problem… ) and the fire place is not working… but it is rather a heating old system, not the a fire place as Spanish people understand. So it is not a real “con” , as the house is wonderfully warm and you don’t need it. We were absolutely happy with the place and will recommend it without a doubt!
