That's great
@CraigM! I'm glad you are off to a great start. Buenos Aires is one of my absolute favorite cities in the world. Glad you also are getting in tennis lessons. My kids play competitive tennis here in the USA. My daughter plays Varsity tennis at high school since she was a Freshman. Tennis lessons there are a great deal. My kids all take lessons when they are in town. We also pay about $25 USD per hour per kid. They take lessons over near the Paseo al Corta shopping mall.
Glad you took my advice for a good massage. That's the first thing I do once I land in Buenos Aires. I usually eat and then head over for a massage with Micaela. Also, her mother Maria is also good. Or there is another Maria there too and you can get a 4 handed massage which isn't too much more than 2 handed. I usually get Micaela and Maria for that and it is well worth it.
Recoleta definitely is my favorite neighborhood and where I lived for so many years and where my office was located. You have some good friends as you're doing the trip right. SottoVoce is one of my all time favorite restaurants. I've hit that place hundreds of times over the past 22 years. I lived close to it so I was there all the time.
Have a great trip Craig and look forward to reading more of your trip reports.
