I only have good things to say about Elaine's place - coexistence with her went without a hitch, and she went above and beyond as a host when some Bay Area disasters struck. The place itself was comfortable, well-equipped and clean.
A word of warning to any other pig-headed walking enthusiasts: Elaine writes in the description that you need a car when staying at her place. I decided to test this assertion, and I can tell you now: Yes, you really really do need a car :) Or else be prepared to make frequent use of ride-sharing services.
