Sarah and Pankaj's place is up on Potrero Hill and even has a glimpse of the Golden Gate Bridge!
The main space (shared with the other 3 or 4 guests) was lovely and homely. Our room was small but comfortable with a great bed and plenty of storage space. We were there for 2 weeks and dispute being warned about it, were not affected by the building work next door.
Sarah and Pankaj are very friendly and helpful giving us tips about the local area (like all you can eat yoga for $25 for 2 weeks down the road.) They were very easy to communicate with and very responsive when we needed anything. I would highly recommend staying with them!
