I stayed with a friend for three days at Moa's place. She was kind enough to arrange us a mattress as her place only has one bed. The apartment itself is in a great location at Kungsholmen with quick access to pretty much everywhere in central Stockholm either by foot or via the underground. The apartment itself was very small, but in good condition overall. We only used it as a base for sleeping and did not spend much time in the apartment itself - I think that if you are planning to cook dinners and spend time indoors the apartment might be a little bit too small for those not travelling alone.

She was very flexible in meeting our arrival times as we had different planes to catch and had no problem giving the keys to my friend arriving earlier than myself, who had actually made the reservation.
