We got there early, about 11:00 am and early check in was no problem at all, even though they were fully booked. Our room was the standard size for a city hotel, (you're not gonna find too many huge hotel rooms in DC unless they are suites). The rooms are equipped with besides the standard, bed, desk, chair, dresser and wardrobe, there's a flat screen HD TV and mini frig also. I called down to request a microwave; they said they would see if there were anymore available. We left the hotel and when we got back, they had set up the microwave for us.
This hotel is one block from a metro stop, which is very convenient. There's a couple of sandwich places nearby and a CVS. However, there isn't any nearby restaurants except the on site Marriott restaurant.
There is on site parking. The parking deck does fill up at night, and they have to valet park your car so you have to leave your keys. I have to say they have the cheapest hotel parking I’ve seen in DC.
The area this hotel is in is right near the new Nationals baseball stadium. There is a lot of new development coming up around the hotel, so I do see restaurants and more stores in the future.
I'm not sure if this hotel is always as busy as it was when we were there because we were there during the Cherry Blossom festival, in the heat of tourist season and with the new baseball stadium there seem to be a game every day. Nevertheless, even with all this people traffic the service was still good.

We were to check in Monday around 10pm, but missed our flight connection & were unable to arrive until 11am on Tuesday. Hotel had a 6pm cancellation policy, but when I called (at 9pm) to explain our circumstances, they waived the cancellation policy (no charge for the missed Monday night) and even let us check in early on Tuesday. What a pleasant surprise!
Very clean (fairly new hotel) & hotel staff was extremely friendly & helpful. Convenience to the Metro was a real bonus! Also only a $15 taxi fare to National Airport. The only down side is the lack of restaurants in the immediate vicinity. The hotel does have a restaurant (OK) & also a snack area to purchase a sandwich/salad, etc. Subway & Five Guys are around the corner. Five Guys has a GREAT hamburger! We would definitely stay here again.

We were quite fortunate to find this hotel. It offered a great deal of positives that we enjoyed: comfortable room, clean environs, great price, close proximity to the Navy Yard Metro station, quiet, in a seemingly growing and rebuilding area and helpfulness with directions and other questions. If there was a downside, it was that the hotel staff were a bit overwhelmed when our cards would not work, coming back from a long day of seeing the sights. However, the manager was apologetic and fairly quick in resolving the issue. Otherwise, a great experience and we would stay again.

We just returned from a 6 night stay at Courtyard Marriott Navy Yard. We really enjoyed the hotel and we are quite picky. Jennifer at front desk was so nice the whole time we were there. The rooms were clean and quiet and new enough to feel brand new. Our room with 2 Queens was quite spacious and my 2 kids enjoyed the indoor pool. Also the breakfast is good and reasonably priced $10 adults $5 kids. Cooked to order eggs and waffles so we were happy. Also great location in that it is as close to metro station as you could ask for and CVS on the corner is too convenient. Buy a case of water and put in the fridge. Overall, we were satisfied with this hotel. Oh, the sheets and pillows were nice. I normally prefer the Westin or Hyatt but these linens were very good. Also, there are 2 washers and dryers available and they give you complimentary laundry products. Oh, they have warm cookies in the afternoon. A nice touch. Good room service menu also.
