The good: The best thing about this hotel is it is brand new. Super clean. Service is very friendly.
Access to the 66 is great. You can get many places easily and are within close distance to both Tysons Corner mall and Fair Oaks mall.
Pool is small but nice and new.
Bad things: Breakfast buffet is the poorest one I have had at any Residence Inn. They ran out of bananas every single day. Really? Bananas? Pretty basic staple if you ask me.
Laundry is $2 per load - very expensive.
If they can get the breakfast kinks worked out, I would give it a better rating.
