Perfect for NIH person.  Rent a room in a safe and quiet Bethesda neighborhood.  You will have your own bedroom and bathroom.  You'll share a kitchen with the homeowner who lives in the home.  No car is needed as you can walk to the J2 bus stop and take it straight to the Medical Center Metro.  The home is also walking distance to the supermarket (Giant), CVS pharmacy and other stores and restaurants.  All utilities and internet are included in the rent.  The homeowner has two medium-sized, friendly canines so keep that in mind.  The homeowner has a doctorate in the sciences and in the past was an NIH fellow for 5 years.  Feel free to email with any questions.
