Just wrapped up an 8 night stay at the Residence Inn Ballston while in town on business. The hotel is only a few months old so the whole place is like new. My room was clean and well equipped - plenty of power outlets, two flat screen TVs, free ethernet connectivity and strong fast Wi-Fi. The kitchen had a full sized fridge/freezer, microwave, cooktop stove, dishwasher and coffee maker.
The gym has three universal type machines, dumbbells to 50#, three treadmills, some bikes and elliptical machines too. Plenty enough stuff for some creative workouts. Plus there's an indoor pool with lifeguard on duty. The laundry facilities are across from the gym and there are 5 good quality front load washers and 5 dryers. There's also soap/dryer sheets for sale in the laundry room. Everything is $1.
The breakfast was always hot and well tended to by the staff. Make your own waffles, and a buffet of scrambled eggs, sausage or ham, potatoes, and a breakfast sandwich that changed each day rounded out the hot food options. There was also fruit, cereal, yogurt, coffee, juice etc. Monday through Wednesday dinner is served free in the dining area. I had it twice - One night was lasagna, one night was barbequed beef. Very good considering the price.
The hotel is a short walk from the mall and plenty of food options. The Ballston Metro Station is a 3-5 minute walk.
Great staff, great location, great business traveler hotel. I hope to return.
