Great location and even better host. Palermo is a beautiful part of town with a good vibe. Close to restaurants, bars and not a far walk from all major tourist destinations. Make sure to bring down all necessary spending cash in USD. Exchange the USD at the blue rate (14 - 14.5) and you are saying yourself a large amount of money by paying in pesos and not on credit card which will charge you official rate (9-9.5).
