Tushara's apartment is an excellent place. It is perfectly located near the Walter E. Convention Center, which has its own Metro stop. Furthermore, there is a small supermarket nearby and a liquor store next to the apartment. Of course, a liquor store attracts its own audience but we really never felt uncomfortably. We did not use the kitchen (except for the fridge) but it seemed that it is fully equipped. More important for us, the Wifi worked very well. We would definitely book it, again.
Tushara is a perfect host. He always responded very fast via AirBNB and was very friendly and helpful. We did not meet in person although he offered it. It was maybe due to our full schedule (conference and sightseeing).
