Have been HHilton honors member for 3 years and stay primarily at Hampton Inns. Was really looking forward to this stay but didn't have the greatest experience; in fact this is my lowest Hampton review ever. Started off by getting a disabled ready room on the 2nd floor which is really ground floor of the alley that is in the back. Dumpster picked up by our window at 04:00 each morning; lovely! There was some sort of frat party in the same alley one night with loud music, drinking, bongo drums - called front desk 3 times to inquire about the noise, each time they said they would investigate and call back; they never did. Breakfast buffet was the stingiest I have ever encountered, waffle batter watered down, had to ask for bread slices and was given them one at a time! And, grossest of all was the woman at the buffet picking up spillover from the corn flakes, cheerios and fruit loops on the counter and placing it back in the dispenser! Asked front desk to order us a cab for the airport and they ordered a limo.
The location was great, very near subway and White House. Be advised, this section of DC rolls up the sidewalks at 6pm and you may need to walk closer to Dupont circle for a meal.
I hope they iron out the wrinkles as it is a great location, has a nice boutique style and majority of staff were very pleasant. Good luck with it.
