I have been using airbnb for a while now and specially in San Francisco I can say with no doubt that Markus' place is the best apartment I have seen and stayed at. Strategically located in the heart of Mission, the apartment is big, bright (lots of natural light), fully equipped and beautifully furnished in a mix of minimal european style and modern art (the artworks all over the flat are an amazing collection). I felt at home from the very beginning and Markus was super nice and friendly. I'd highly recommend his place!
