The house has everything we could have wished for.
We were traveling with 8 people including for attending a conference in Stockholm. We found with Christer a perfect host.
The house is very clean and has all the service, ranging from very nice Terrace, Jacuzzi and Sauna, all there.
The connection to the city center is very good. The metro runs every 10-15 minutes and you are in about 15 minutes in the old town.
This is most likely one of the best spots you can find for a visit to Stockholm.
