My daughter & I stayed here for one week in August. The place is wonderful and clean and exactly as described. It is a 5 minutes walk to the back entrance to the Zoo, and a 15-20 minute walk to various metro stations. It is a short walk to shops, etc. Rock Creek Park is nearby, which is a great place to wander and escape the city.
Cecily was very responsive, ensuring that our stay was pleasant and check-in and check-out were smooth.
The windows have fly-screens on them, which keep out the bugs. I was pleasantly surprised at how bugless it was, considering it's a basement apartment in a hot-and-humid climate.
Our only regret is that we weren't able to stay longer!
