Mark out-hosted any prior AirB&B experience I've had. I was in San Francisco looking for a permanent residence and I couldn't have wished for better. Mark is very helpful, knows the area like his pocket, has great advice if you're not used to the US, cooks wonderful dinners, he's full of joy and made sure I had everything I needed.

The apartment is located in the heart of the mission which is perfect for just about everything (including a bunch of tech-shuttles). I strongly recommend staying with Mark if you're new to the city, I could have chosen a solo AirB&B and I'm glad I didn't.
