I have yet to find another hotel which has made me feel as welcome and well cared for as Bobo Hotel. My husband and I visited the hotel twice on our honeymoon and the staff basically worked as our own 'personal assistant' for most of the time helping us organise tours etc on our trip. Nothing was too much trouble.

We stayed in the Argentina Suite which was fab with it's own large jacuzzi and terrace. We also stayed in the Pop room which was good too, and the classic - not so good because the speakers in the bar downstairs must be fixed to the ceiling by this room and are quite loud during the evening, but fine if your out to 2-3am which you should be in BA anyway!
Basically this is a gem of a hotel and definately the best place to stay in Buenos Aires.
