The staff at the Tango de Mayo Hotel is first rate, all very helpful and gracious. The hotel is in a nice, central location, and while the number of top rated restaurants are reached not by foot, but by Subte, bus or taxi, it is still very convenient. We enjoyed our very large room and the delicious breakfast. While there is some street noise, expected in any city, there is no noise from other guests. I would stay again at the Hotel Tango de Mayo when in Buenos Aires.
