Carlos was the consummate host! He picked us up from and returned us to the airport. He was always available to answer any questions and address any concerns. He took us to get the best exchange rate, helped us st up a phone for while we were there by getting us a SIM card and minutes for the I phone. He had a full list if places to go, things to do and see for us on arrival.He Sat down with us and a map the day we arrived and mapped out everything for us.I highly recommend Carlos to anyone visiting Buenos Aires. What a truly kind, caring, thoughtful, and sincere man! We will be back and we will rent from him again!!!
