A friend and I stayed 3 nights midweek at Houcine's apartment while visiting the Smithsonian Institution on the mall. The apartment is as described, with two bedrooms, a well appointed bathroom with excellent shower, and kitchen that seemed to have everything we would have needed if we had cooked. I can say that the coffee maker makes good coffee. The internet and the large television worked well, the couch was comfortable and there were plenty of utensils, glasses and cups. Refreshments and a filtered carafe were in the fridge. This apartment was designed with visitors in mind and I can not think of anything that is missing. It was very clean. It is on the lower (ground) level of a three floor building; Houcine is above. There was no noise to speak of either from above or the street while we were there.
The location is a block or so from a commercial street with a number of restaurants and markets. We used Lyft to get to the museum which took a few minutes and cost around $8; the car arrived within 3 minutes every time. For our purposes the location was excellent; DCA was roughly 20-30 minutes and around $20, again using Lyft. Public transport is nearby, but we didn't try it.
Houcine greeted us when we arrived and explained how the keypad worked for entry. he was upstairs and available by telephone if we needed anything (which we did not) and was very friendly and forthcoming. He is the best airbnb host I have encountered to date.
I recommend Houcine and his apartment very highly and without any reservations. I will certainly try to stay there again when I visit DC.
