This was a great place to stay for my 48 hours in Stockholm. The building itself is nice, with shared balconies on one side and private ones on each appartment, offering some lovley views (and if you're lucky, you may see some little birds visiting the balcony). It's a nice area to stay, not too busy but within easy reach of the Tunnelbana, or you can take a lovely walk along the waterfront towards the historic city centre, and see all of the unique houseboats that are lined up on the waterside. Although I didn't get to meet Erika, she really went out of her way to offer suggestions and advice, which was much appreciated.
I will note that you need to be able to climb a ladder to access the bed, and there is some background noise from the building itself (it is not totally silent), but for me this was fine.
