Spectacular place, in a great location. Spotlessly clean, and very nice high end fixtures. Right in the heart of Dupont Circle, it is very close to public transportation, but also in walking distance of several nice restaurants and bars. Really enjoyed our stay here. Communication with the landlord was very easy and so was check-in/check-out process.
One drawback was that the unit was on the third floor (with a convenient elevator), but the first and second floors of the building are actually a bar which stays open til 3am on weekends. We were aware that we were booking a place in a happening area in a major city, but this was a bit much. Also, the master bedroom overlooks a small parking area with 8 dumpsters, where the bars dump their glass bottles. Not the end of the world, but something to be aware of.
All in all though, we did really like it, and would recommend it to anyone wanting to stay a weekend in DC!
