While apprensive at first following negative statements about the area by my taxi driver, I found a very nice place situated close to a subway station and many bus lines, and less than 15$ by taxi from downtown.
Kim had been accomodating toward my schedule, allowing me to drop my bags earlier than her usual welcome hour so that I might be on business ASAP (in my case : visiting museums). She also made it a point despite a busy Schedule to check whether everything was alright for me, a point much appreciated.
While one may always found détails that might be improved, one must say that Kim and her place delivered everything they promised and are a good base from where to explore DC.
