I never expected to be giving a Residence Inn a 5-circle rating, but this one certainly deserves it. All other Residence Inns I have stayed in have been mostly (if not all) a little tired looking, and pretty solidly in the 3-circle category at best. This one breaks that mold entirely.
My room (a studio) looked almost brand new, was immaculately clean, and very well-furnished. The kitchen looked great too, and had everything necessary for some light meal preparation. They will even pick up groceries for you, which is a nice service (though I did not use it).
The bathroom facilities are also immaculately clean, great water pressure in the shower, and I like having the sink separate from the toilet/shower area. One of my other favorite features was the safe in the closet. It is narrow but tall, and easily fit my laptop, which I appreciated. The bed was also comfortable, with plenty of outlets around.
Breakfast downstairs was also very well done. They have a large seating area, which makes it possible to sit near the TV if you want to hear the morning news, or far enough away that it doesn't bother you if you want a quiet meal. There is a selection of hot items (breakfast sandwiches, eggs, etc.), plus cereal, oatmeal, fruit, yogurt, etc. They also have a waffle maker, and someone there to make them for you and bring them to you. All employees were very nice and helpful.
And finally, the location is great. Steps from the Courthouse Metro stop, and a very short walk to great restaurants and shopping (including the Apple Store). Prices are steep because of that great location, but this hotel is worth the price. I will definitely stay here again when in the area!
