Betsy‘s place can’t be any better to explore Washington from a perfect base! We (two adults and two children) stayed there for four nights and above all, the location is possible. We walked to the Mall or took the free bus.
The apartment is indeed well lit through many windows is greatly equipped with everything one needs during a stay (including washing machine and dryer).
Communication with Betsy was always fast and she is a most helpful person.
Highly recommend!!
