I'm glad I met Faysel and could receive excellent accomodations at his home. Location might look a bit off the way to businesses and transportation, but nothing much if you are willing to walk 400 m to main city bus lines or 900 m to nearest metro station. Both means can quickly bring you to convenient downtown areas where you can find intense cultural life in DC. More importantly, my host has been strongly helpful to all of my needs as well as even warm and friendly beyond my own expections.
