We are a family of 4 (2 adults, 2 kids) who stayed here in April on our annual Washington trip. In reading the reviews, I had high expectations and was not disappointed.

Pros
1) Location, Location, Location! - The hotel is walking distance to the National Mall, the White House, Washington Monument , museums etc. It's in a nicer area and has several stores and restaurants within walking distance which is a huge plus.
2) Pool - great because it rained one day we were there and the kids had a blast in the pool
3) Rooms are clean - and were large enough. We stayed at the Sheraton 4 corners 1 year and the rooms over there were the size of a shoebox. The rooms at the Marriott were of a decent size. The bathroom was very clean and larger that other Washington Dc hotels I've been to
4) Breakfast Buffet was good and had plenty of choices - eggs made to order, fruit, yogurt, french toast, quiche, cereal, bacon, bagels etc..
5) Nice staff - they even allowed us to check out late which allowed us another day to enjoy the museums

Cons
1) This is not a "real" con but when we pulled up to the hotel, there was no one there to tell us what to do with our car. There is no "hotel parking", it's all valet, but we were slightly confused when we pulled up. There was a guy there but he he didn't approach us until after I got out of the car, walked in the hotel and inquired with the front desk.
2) Breakfast Buffet can be expensive. Our rate came with breakfast coupons but I saw what the bill would have been if we didn't have coupons and it would have been $50 for 2 adults and 2 kids (1 of whom is a toddler)

All in all, of all the hotels I stayed in in DC, this one was my favorites mainly due to its location. I even liked it better than the Sofitel for traveling with my family because of the many things to do in the area and because my kids enjoyed the pool.

We stayed here in mid-March for 3 days -- loved the location and the staff was top-deck. We truly loved this hotel and felt at home and wanted at this property.

As others said, the rooms, although lovely, are not huge but suited our lodging needs (2 adults, 1 son). There is a Macy's across the street (in case you forget your swimsuits as we did). Metro stop is right outside the main entry.

A nice, safe area. Good breakfast buffett.

Will definitely stay here again should our travel take us to this area again.

We drove to Washington D. C. for a weekend visit to take in the Monuments, Memorials and Museums. We researched all of the downtown hotels by location and chose the Marriott at Metro Center which seemed to be one of the most convenient and affordable. We usually stay at 4 star hotels such as the Four Seasons or The Ritz Carltons. We were surprised and extremely happy with our stay at the Marriott at Metro Center. This Hotel was in walking distance of the Smithsonian Museums, White House, Monuments and the Metro. The staff members were amazing and were very personable and helpful. In fact, Erick Mendizabel, Concierge, came through with lots of suggestions, and when we had problems figuring out how to use the Metro, he personally walked us to the Metro Station to assist us in purchasing our Metro fare passes, this was over the top service!!! Jay at the front desk was always smiling and just happy to greet you after your day. Jay and Erick were always ready to suggest places to eat and advise whether or not to walk or take the taxi or Metro. So I guess you can tell the service was more than we expected. The hotel was secure and safe. There were employees positioned at all entrances and security was stationed at the elevators. Finally, the hotel, is being slightly remodeled, but you won't even notice. The only reason we knew about the remodel was that we were told by an employee and there was a sign posted. The hotel facility is just perfect. The hotel was immaculate and so was our room. We had two double beds which were super cozy and our room and bathroom were spotless. The gym had all the right equipment and the pool looked relaxing and calm. The number one reason we stayed at this hotel was the location. You can walk to Chinatown, the Verizon Center and all of the historic sites. Multiple highly rated restaurants in Fodors and Fromers are in walking distance from the hotel. You can walk to Tosca, Caucus Room , The Occidental Grill, Clydes, The Old Ebbitt Grill Room, Matchbox and so many more. We were recommended this hotel by a friend and we will now highly recommend this hotel to you. For the price, amentities, service and location this hotel can't be beat, if you want to see it all and do it all you should stay at the Marriott at Metro Center.

The Marriott Metro Center is an outstanding Marriott in Washington DC. The rooms are up to date and confortable - nice beds, high quality sheets. Good lighting in rooms. After you fork over $9.95, internet is unlimited as is local and long distance calling within the US.

The location is great - on the same block as a major metro stop and across the street from Macy's and near other shopping, dining. You will have no trouble going places from here whether by cab, by metro or on foot.

Staff - nice, courteous. Room service breakfast - good if pricey.

Best feature - the fantastic workout room. Head and shoulders better than the average hotel with weight machines, free weights and many cardio machines all with their own TV. Water purifier, towels. Very clean.

Highly recommended.
