We had a great time staying in Christian's apartment. He was a wonderful host--friendly and helpful up the four flights of stairs to his apartment. It is a two level apartment with two full bathrooms, 4 bedrooms and two beautiful balconies. It was a perfect location for our conference at Karolinska Institute (about a 10 minute walk) and an easy walk (20 minutes) or subway ride into the center of Stockholm. The Arlanda airport bus stops at St. Eriksplan which is within walking distance to the apartment. We will gladly stay at his place when we visit Stockholm again.
