Mark and Sarah's place has everything you need. The kitchen was good, although I didn't use it much. Frankly I was there on a work trip and didn't spend much time there. But checkin was easy, they were responsive, and their dog is awesome. If you don't know SF, it's not super central/walkable. If you do know SF, it's up on the top of Potrero Hill (something to think about if you have a bike like I did). You have to park your bike outside somewhere if you ride a bike but it's a really safe neighborhood. I say "not walkable" but there's a great store on the corner and lots of restaurants nearby. It's just hilly and not high density. My office is in SoMA so it was perfect for accessing that part of town or getting to the Mission. I'd stay there again.
