Dear FT travellers: I've been corresponding with Dante http://dantesairporttransfers.hazedaze.com/, who is recommended in this site. (BTW, he's quick to return emails.) My partner and I have set up a milonga evening with him for next week. He's going to pick us up at a restaurant, take us to a milonga place (or two?) and then take us back to the hotel. Very reasonably priced. He also agreed to give us a city tour for US$40 for 3-4 hours. Unfortunately, he was booked for the time we requested and we're going with a different (and more expensive) tour company. I'll post about my experiences after we return from our trip the second half of December. Adios!
