You cannot beat the location of the Hyatt Arlington for convenience. It is a few short steps to the Rosslyn Metro station, giving you easy access to all of DC as well as Reagan National Airport. Our extended family traveled to DC to visit my son, reserving 4 rooms. The hotel was kind enough to place all of us together, which made coordination of 8 people (4 of whom were elderly) considerably easier. The rooms appear to have been recently updated, with crisp furnishings, fresh white linens, and granite counter tops in the bathrooms. The rooms were clean and quiet and the beds were very comfortable. The rooms had the usual accoutrements, including a safe large enough for storing iPads and cameras, and a small refrigerator. The front desk staff was extremely friendly and professional and was particularly accommodating with all of our inquiries - everyone was a delight.
As a large group, we were mindful that we needed to make advance dining arrangements for most meals. Although we ate dinners and lunch in the city, we took advantage of the breakfast buffet in the Cityhouse restaurant at the Hyatt on two mornings and were given a private room to accommodate us, which worked perfectly. The buffet included an omelet station, waffles, scrambled eggs, hash browns, bacon and sausage, breakfast breads, as well as yogurts, cereal and a variety of fresh fruit - certainly varied enough that everyone found something they were happy to be eating. All of the food was well prepared and delicious. The staff in the restaurant were all friendly and professional, from the hostess to the waitstaff to the chef who manned the omelet station.
We will be returning to DC in another month and will be staying at the Hyatt again.
