I loved the location of the unit, close to the downtown area and in a nice neighborhood. You can walk safely back and forth to the Metro if you choose to, even at night. I also liked how clean and well-appointed the apartment is. Comfortable bed, great decor, thoughtful library, nice bathroom... everything. The entry was a little tricky for me on a rainy, dark night with the 2 combination entries and the location of the fence that is the entry, but the host provides a lot of help to make it work.
I also loved the fact that the unit was just as I pictured it... no big surprises at the end of a long day.
