Impeccably clean and functional, with a full kitchen and comfy lounge. 8 minutes walk from Mt Vernon Square metro station and the convention center, 10 minutes from Chinatown and its dumplings. The immediate neighborhood isn't particularly inviting and is even a bit complicated to navigate but it felt safe enough, and the bright lights of K street are within 2 blocks. Overall a vastly, vastly better choice than the creepy slums which pass for hotels in D.C. under $150 a night. I'll definitely consider it again for business in the area.
Sole problem: A first set of instructions sent 2 days before check-in contained the wrong door code and no contact details. This was promptly corrected, but in my case too late to avoid some trepidation, until I could get hold of the second message that did contain the right instructions, and thoughtfully included no less than three contact numbers. Too bad, I had skipped that one before leaving, thinking what I had was the final word. I suppose it was an automated procedure gone wrong and will now be fixed, but until it is, beware of the T-2 days message.
