This flat is on the 4th floor of a cool building in a prime location in Gamla Stan, just one stop on the T from Stockholm Central Station and within walking distance to many attractions. The beds were comfortable and the flat was clean and modern. The spiral staircase is a bit treacherous for children (we had 2 toddlers) but is manageable. Katia was super helpful in the beginning of our stay but became unreachable at the end after my 2 year old daughter found a plastic bag of white powder (?!) and a rolled up 20 kronor bill in a decorative plant on a shelf within her reach. This was extremely alarming and is a safety concern for those traveling with children. Other than that, our stay here was excellent.
