Though I didn't meet Birger in person, I can feel he is a bright and neat person by the house of his. Exactly like photos, the house is modern, clean and very comfortable. I had a very relaxing two nights stay there. The house is close to the main station and a bit distant from the historic center, you could take a tram there in 10 mins or about 30 mins walk.
Birger emailed me a very detailed instruction of the house, I had no problems to find and get in the place. Everything is perfect, thanks Birger!! :))
