The flat is in a very convenient location in Södermalm, close to shops, restaurants and the metro. Communication was a bit tricky - I had planned to do something in Stockholm on my arrival day, but was informed quite late on the evening before my arrival that I was to appear at the flat at a specific time. I had to change my plans.
The flat has everything one needs, but is a bit dirty. Overall, however, it represents a pretty good value for Stockholm, which of course is very expensive.
