The hotel was in a great location, close to the subway and Santa Fe street, with lots of great restaurants and shops around. The rooms were pretty spacious for being in the center of the city, and we really liked the jacuzzi tub that we had in the room. There was a pretty nice hotel bar in the basement (fairly quiet), and the breakfast buffet was very nice. We really liked that breakfast was open all day and the checkout time wasn't til noon, so we could sleep in without worrying.
There was also a very cool cafe/bar a block or two away called Clasica y Moderna that is also a very old bookstore.
