The house is in a great shape, provides lots of seating opportunities in all three floors, music in all rooms, perfect WLAN, nice kitchen - it includes everything you need. The sleeping rooms are a bit small, but there are enough of them with close-by bathrooms.
The only thing we disliked was the traffic noise from the street next to the house, which made us having our meals inside and not on the balcony or in the garden.
The surrounding area is extremly nice, you can go for nice walks, can get in 10 minutes by car to a very nice beach (in the direction to Elfvik). Supermarkets are on the south of the Lidingö island.
A trip to Stockholm is easy to do (either by bus or by car to Ropsten and then with the city train), the Tyresta national park is 45 minutes by car, the Björnö park is about 1 hour by car. Both parks are extremly nice - do not miss to visit them.
