My father, family friends and I had a really lovely stay here! The location was ideally situated to all the comforts and beautiful sights of Gamla Stan (which is especially gorgeous during the Christmas markets in December).
The bedroom arrangements were perfect for four adults, and gave us each plenty of privacy, while the common sitting room was a wonderful and cozy spot for us all to sit around chatting and drinking coffee from the kitchenette. I was also impressed to see that the place includes a full washer/dryer, an exercise machine, and other amenities that made us marvel at how these things were brought up so many flights of stairs.
Oh, and do be aware, if you have mobility issues: I really mean *stairs*! We got a good workout going up four flights every day, because most old buildings in Stockholm are configured this way. For us, it was not a problem aside from lugging suitcases up with us. And even though Gamla Stan is a busy area of town, there was no noise from the street that we could hear from all the way up on the top floor, so that was a pleasant feature!
There were multiple hosts for this property, meaning that their welcome email was comprehensive and very helpful, and their responses were timely. We'd certainly book here again!
