I cannot recommend Ariel enough- he went above and beyond on numerous occasions to be flexible with arrangements, gave detailed instructions of how to get from the airport to his place and spoke good English (better than most in BA). The place was clean, and in a great location (very close to the bus, metro, supermarket and many attractions in the area), the only downside was that the bathroom was a little small, however, we expected this so we weren't disappointed. Thank you Ariel for a great stay!
