We had a very pleasant stay in Ludvig's apartment. Close to the T-Bana with good links to central Stockholm, close to a supermarket. Easy access to Liljeholmen Flygbussarna station (convenient bus link to Arlanda airport) The apartment is pleasant, clean, in a quiet area, and has everything you may need. We didn't met Ludvig but he has been very responsive to our requests before and during our stay.
We definitely recommend this place.
