As previous reviewers mentioned, the place has no lift and climbing stairs could be somewhat problematic for people with limited mobility and lots of luggage.
Nevertheless, it has by far exceeded our expectations - it's relatively spacious, very clean and perfectly located. I wish we could spend a week there in the very heart of old Stockholm. Great for explorers and those who could appreciate the charm and feel of centuries. Our kid was so found of the upstairs bedroom with vaulted ceiling and the view from the balcony. He truly believed we stayed just next door to Astrid Lindgren's Karlsson-on-the-Roof.
Also wanted to mention the hospitality of Robert the host. He was very quick to reply and provide us with everything we needed for our stay. Much appreciated!
Will be happy to come back again someday.
