I stayed at David's fopr two nights. He has a homely flat on the north side of Stockholm: it's three stops on the metro from the central station and a five to ten minute walk (the walk back into the city centre takes about 45 minutes and is all downhill, so that's easy too). There is a large park very nearby which I didn't get chance to explore properly, and lots of places to eat. The bedroom is large and airy, and the bed comfortable. I also had use of the bathroom and kitchen while I was there. David and Emma were not at home much and so I had the place to myself. David gave me some useful advice for travelling back to the airport that saved me some money. He also recommended the Vasa ship museum as a must-see and it was definitely worth it. The fact was just right for my stay.
