We had an excellent week-long stay in this home in the Mt. Pleasant area of DC. It was a perfect fit for my family of six - grandparents got the master bedroom, parents got the guest bedroom with queen bed, and teens got the bedroom with twin beds. We enjoyed having a kitchen so we didn't have to eat every meal out, and it was nice to be able to spread out a bit rather than being on top of each other in a hotel.
We were pleased with the location. It feels very safe and residential. We enjoyed the walk to the metro station every day where we got to see locals walking their dogs, running, etc. Do be aware that this is not within easy walking distance of restaurants or shopping, but if the 1/2 mile walk to the metro does not bother you, you can get anywhere you need to go. The house is a very close walk to the zoo, so we enjoyed that. I would stay here again.
