Again, Barrio Norte is the bubble. Is everybody in this forum rich? Well, if you like old women with tiny dogs and plastic surgeries Barrio Norte-Recoleta is the right place for you. If you are going for a place in the "bubble" for young people go directly to Palermo-Las Cañitas; if you like more gritty but touristy go for San Telmo (and is close to your job); if you like more authentic and central go for Abasto and maybe Caballito (the former is good if you like off-theater and alternative bars, the later has nice parks and it is an urban center in its own); if you want to be close to Palermo but experience a "real" barrio, go for Villa Crespo; if you like Tango and want a non-touristy place in the forbidden zone for rich expats, go for Boedo (you see, it is south of Cordoba Avenue, the limit of the bubble); if you want to live in a town inside the city go for Devoto; if you want middle-upper class ambiance and expectations, including paranoia, fashion, and macrobiotic restaurants, go for Belgrano and its sub-neighborhoods. Take a map of the city, decide how much time do you want to spend in public transportation each day (trains are faster, closer to metro lines is better), draw a circle, and choose according to your tastes.
