Nancy is an outstanding zero-stress host with an awesome live-and-let-live world view and is 100% on top of her gig - this is a super easy host to deal with and a super easy place to book. Her house is just a beautiful home away from home - my room was bigger than it looks in the pics, had a walk-in closet the size of my kitchen, super comfy armchair, big desk, plenty of light and air and good internet. Apart from being a coupla blocks from the a BART station (which is only 10-15 mins from SFO) is also at the top of the Mission (between Mission St if you dig that gritty authentic Mish atmos or Valencia St for the brighter flipside of the same coin). From this spot there's pretty much nothing you can't get within a 10-15 min walking radius - eg the indie Roxie cinema, The Chapel (outstanding indie music venue), Dog-Earred books (one of the best indie bookshops in the US), Elbo Room (old-school dive-bar & rock music stage). Plus the BART will get you downtown in 5 mins for $2.50 (I went from Nancy's place to SF MOMA - door to door - in under 20 mins!) or walk up to Church St to get the J Line into the Castro and downtown or head the other way to the beach. This my Go-To SF place from now
