A friend of mine and I went to Stockholm for four days, but wanted an affordable place. That's why we choose this place. Plus, Sven's place is located in a very quiet area (and near a park) !
The apartment is close to the public transports (a bus line one-minute walking away and metro six-seven-minute walking away).
Even though we rent a room, we didn't see Sven often, which let us privacy and so on. Something one can appreciate, I guess. But he did help us find the flat when we arrived in Stockholm, and helps us with few informations about our trip (visit, transport, etc.)
In general, I will recommend this place !
