it's marriott. its going to be nice, it better be nice for $300 a night. bed is great, kitchens are wonderful for dinners in the room. this location has a grocery store less than a mile from the hotel. enormous fitness center with 6 treadmills and 5 elliptical, full weights, hard to find. 37 inch TV.
negatives- not cheap- Its DC. they charge ~$20 per day parking. laundry is $3 load. free breakfast is daily, but "social hour" which is another name for "free dinner" is only mon-wed. Free dinner is a good idea until you see what they have...not recommended.
