We've spent several weeks in Sandra's apartment. Overall, the apartment is well equipped and spacious enough for two people who want to stay for a longer period. Some furniture is a bit used and could need a replacement. We communicated this to our host Sandra and she promised to look after it. In general, Sandra was very responsive and helpful and solved any issues we had fast.
The location of the apartment is good, with three metro stations and Södermalm in walking distance. The large street, which runs behind the building, is clearly audible with windows open, but not an issue with windows closed. It did, however, stopped us from using the balcony more frequently.
Overall a fine apartment for a longer stay in Stockholm.
