Mark's place is in a great location. Nice neighborhood. We were initially concerned about street parking a $100K plus vehicle, but it was one of many, and never saw any sign of crime or vandals. Not a very busy street. The street like many in SF is very steep. Take Uber unless you are very confident in your ability to parallel park on an extreme hill. I would not recommend the location to any one with knee or hip problems. The decor we found to be delightfully simple, with the large framed SF map especially interesting. Comfortable bed and pillows. Nice little fridge, Keurig unit, and toiletries provided. Mark was a very accommodating, a gracious host.
