Bethesda Doorstep is Cam Gohari's family of furnished homes in downtown Bethesda and Chevy Chase. Four two-bedroom apartments fill a renovated brick house on Avondale Street, three minutes from the Red Line, and two of them can be booked together for ten. Three more sit on quieter streets to the south, from a lower-level one-bedroom to 1,700 square feet with two en-suite bedrooms. Every one has a full kitchen and a washer and dryer.
