We were here for over a week while moving to the area, so we were able to fully appreciate all the hotel had to offer. The staff went out of their way to be helpful. We had things sent via Fed Ex to us at the hotel and they were brought up to the room. When I was eating a meal by myself with an 8 month old in tow, the staff (including a manager) acted like an extra set if hands: setting up the high chair for me, putting fruit in a bowl, and getting me a to-go cup for coffee. They let me borrow scissors to cut coupons from the Sunday paper. They carry the Washington Post and USA today, which for someone stuck in the Deep South for a few years, was a nice bonus.
The evening social meals (Monday-Thursday) help take the bite out of the price, which is a good value for this area. (the government rate was $179/night). The layout of the 2-room suite made it easy to have two cats and a baby and have everyone get much-needed sleep. There is room in the closet for two cat carriers, and space in the bathroom for a litter box. If you're a dog person, there is plenty of green space nearby for dogs to do their business, and also good places for walks.
Everyone knows traffic in DC sucks, but this hotel is in the perfect spot. Sure, if you go to check in and come off of 28, merging over to the turn lane might be rough. However, once you are here, you can walk to more than 5 restaurants (Red Robin, Dave's Famous BBQ, Ghengis Grill, Chipotle, etc) a Target (with a lot of grocery items), Starbucks (in room coffee is actually really good. If you don't like creamer, steal some milk from breakfast, the staff won't say anything), a hair salon...you get the idea. Going back out onto Lee-Jackson during rush hour to get food is an exercise in futility. You'll probably average 3-5 mph.
My husband has travelled a lot for business in the last decade. He is sort of obsessed with Marriott hotels. They have comfy beds, nice pillows, easy reservations and checkin/out procedures. Everyone we've encountered is nice and professional. I even saw them find a room for an exhausted soldier asking for an early check in at 0845. They even had staff hold breakfast for him (it runs 6-9 on weekdays).
