Thanks to Gaunch100k for this thread and all the useful information that I learned by reading it. I just returned from 4 days in BA and I enjoyed it quite a bit. You can spend a day just visiting each of the individual neighborhoods Recoleta, San Telmo, Palermo to name a few each have their own character and lots to explore. I stayed in the Loi Suites in Recoleta and can recommend the hotel. The rooms are a bit small, but the lobby and breakfeast area are superb. Got a $127 pre-paid deal through Expedia, which was a pretty good deal. One word of caution is that when paying for a taxi from Bellas Artes to La Boca the taxi driver swapped my Argentinian pesos for fake peso bills. He told me the first bill I gave him was fake, so I gave him another and again he stated that one was fake. It was all very innocent and I did not realize until later that he was swapping my bills for fake ones. I now have some souveneir fake currency

. Don't let this be a deterrent to visiting BA, but just warning about something that can happen anywhere while traveling away from home.
