My stay at Rachid's place was my first time using AirBnB and doing so was a pleasure. I was a little nervous staying at someone else's place whi I didn't know, but he made me feel very welcome, was friendly when I saw him, and didn't seem to be offended that -after a long day at a conference- I tended to hide in my room and relax. Great room; as advertised. And I had a great bathroom all to myself (that shower head is great!). I tend to walk quick, but it was probably 15 minutes (really maybe a little less) to walk to the Walter E Washington Convention Center. Safe walk too. Both Rachid's place and the Convention Center are near some fun parts of town, which is nice. I found a few great places to hang (though I didn't stay late) in between his place and and and the Convention Center, which was perfect.
I also want to thank him for letting me stay, even though I had never AirBnB-ed before and didn't have any reviews! If I ever need to AirBnB in DC again: I hope his place is available.
