Ann and Gunnar are excellent hosts and we had a wonderful stay at their house. They met us on our arrival and gave us a tour of the place before leaving us to settle in. We needed to contact them a couple of times and they were very responsive and helpful, nothing was too much trouble.
The house is very comfortable and homely, it has everything that you need. The shower is excellent and the beds comfortable.
The house is a 5 minute walk to the train station where you can get very frequent trains to Stockholm centre, it takes about 15 minutes. The train is also direct to Arlanda Airport, get the commuter train not the Arlanda Express. You can get a 4 or 7 day travel card which allows you unlimited travel on public transport which includes the commuter train, the trams, the buses, the underground and the commuter ferries - we found this to be excellent value for our stay.
We enjoyed the bread and pastries from the bakery near Älvsjö train station and used the Co-op to stock up on Swedish snacks!
The favourite parts of our trip were the Vasa Museum, the Skansen open air museum and riding the commuter ferries.
