I would thoroughly recommend the NH Atlanta, though we found our room (on the street) a little noisy, but we do go to bed early. Breakfast great, and the view from the dining room is lovely. The hotel is centrally located & easy to get to.
I don't know the price in US dollars. In Euros we paid 84 for a double room/night, breakfast was extra.
Careful! breakfast is more expensive in the week than on weekends.
When we were staying there was a "happy hour" where tapas were free. You can't ask for more than that. The fitness room was really very well equipped. Theme: HotelComparison: about averageDirections: in the Monnaie district.
