I'm a recent MD grad spending a year split between DC and SF in a fun job at the intersection of medicine and technology/startups. My favorite part about traveling is eating my way through new places. I've lived in lots of different countries, and been both a couch surfer and host of travelers.
My husband and I have a wonderful and very large (by San Francisco standards) apartment that we rent periodically when traveling.
Feel free to Google me at Rebecca Mitchell or Rebecca Coelius when doing your due diligence!
