My partner and I just spent 5 nights in Lynn and Mark's place and thoroughly enjoyed it. For starters the location is great, bang in the middle of Haight Ashbury, The Mission and Hayes Valley, we were able to walk everywhere. The flat itself was spacious, light and very comfortable. The bed was extremely comfy and the fact that the flat had a fully working kitchen meant we could make a few evening meals and breakfasts at home (eating out every night when travelling gets a bit much!). We'd most definitely stay again.
