As a couple, we have stayed in 8 Airbnb apartments in Sodermalm in the past 7 years. This apartment is one of the best. The location is on the water at the entrance bridge to the small island of Reimersholme, and the #66 and #54 buses stop a 2 minute walk from the door. It is a very short walk to the bridge to Langholmen, a beautiful place to walk. Hornstull station is about a 10 minute walk. You can sit on the balcony, which faces west, and watch people stroll and run along the waterfront, watch kayakers and see many birds including herons.
All of the expected amenities are present except for a washing machine. Because there is no access to the laundry, this could be a problem for some as there aren't many laundromats in Stockholm. The apartment was very clean and has lots of natural light and is thus bright and cheerful.
The kitchen is not well-provisioned for cooking in terms of equipment and some basics like some cooking oil would be good. This is because nobody lives in the apt.
We recommend staying here, and would do so again.
