Desi was very responsive and flexible. My family was arriving DC on 4 different flights during hectic holiday travel and I made several arrival time changes/requests.
The house was very clean. It was cozy, yet spacious and not cluttered. The mattresses and bedding felt high quality and comfortable. Extra topper for the queen pull out sofa was a nice bonus. Bath towels were fresh and fluffy.
We did not hear noise (voices/footsteps/TV) between upstairs and downstairs. Neighborhood was generally quiet and felt safe. Use your flashlights when walking at night - brick sidewalks are full of "character" and not well lit. We made use of nearby walk to convenient store, Chinese restaurant, bus stop, and 10-15 minute walk to Howard/Shaw metro stop.
We would definitely return and recommend.
