You're just like I am. I'm a city girl through and through and friends think I'm nuts because I take vacations to places like NYC and London.
Buenos Aires is delightful and I think you'd really like it. (If it hasn't changed too much in the last few years since I've been...) Calle Florida (Florida St.) is a pedestrian street with shops, restaurants, bars, etc. that is a must-see for tourists. So is attending a tango show. There are a lot of them available, and I liked a place called Senor Tango the best. You have to go to the Recolets part of town with its off-the-wall shops and more restaurants. It's also where Evita's tomb is.
Dang...now I'm getting all nostalgic for Argentina...I musn't look out of a window right now and be reminded where I really am...LOL.
I hope to entice my adult daughter to come with me. And her stepsister, who's a pilot for Delta. My bait is the Tango! My kid was a professional dancer in her 20s, and she could pick it up quickly and I could fake it until I make it, if ever. Let them laugh!
So, Allegra, maybe you'd like to join the party? If it happens? Four Republican grrrrrls on the loose in Buenos Aires, tall, dark handsome waiters, passionate strangers, great music, dancing and laughing til dawn. I found a good looking 3-bdr BA condo for rent at eBAy of all places, as I recall near Recoleta area, rentable by the day or week or month. Very reasonable, quite complimentary reviews.
