We enjoyed our brief stay at Kelly's condo; the location is unbeatable for those who enjoy walking to restaurants and nightlife, and is also a short walk to a couple metro stations and lines. The strong air conditioning was very much appreciated in the muggy summer days as well. Kelly was very responsive and provided us with a great amount of flexibility when it came to check in and out times/luggage storage.
Note for folks who plan to use the internet heavily: we found the WiFi a bit slow (6 Mbps download speed even after resetting the router), but it would be fine for casual browsing.
