Exactly what you would expect from a Four Seasons. Wonderful service, excellent rooms. Our flight from the states was 12 hours late. Instead of having an overnight flight with our three daughters (ages 10, 8 and 4), we flew throughout the day and everyone was pretty beat by the end of it.
However, standing at the airport was the driver from the Four Seasons, with cool towels and bottles of water for each of us. Absolutely delightful! We had a suite and connecting room for the children. Our room included a large, hydrotherapy soaking tub. There was a charming note welcoming us to South America, with a calming candle and "jet lag" bath salts. Front desk recommended a delightful restaurant just down the street.
We only stayed at the Four Seasons BA our first evening in Argentina and then we transferred to the Four Seasons in Carmelo, Uruguay (see my review - this was spectacular!). The next day was one of my daughter's birthdays. The server in the restaurant brought her a cake for breakfast. The girls then went swimming. When one of her sisters tried to take the ball away from her, she said "Hey, its my birthday". Within 10 minutes, the pool attendant had brought her another cake. Everyone who saw her said "Happy Birthday, Ally". I swear she felt like Hannah Montana! The FS in Uruguay had similar, over-the-top, wonderful birthday service.
I would highly recommend this hotel. Unfortunately, when we returned to Buenos Aires after our stay in Uruguay, we stayed at the Sheraton Libertor (the FS in BA is definitely pricey) and had a horrible experience.
If you are transfering to Uruguay, we took the ferry one way and the flight the other. Of course, the ferry took longer and was extremely crowded so go early to get seats together. Also, we could not purchase anything at the snack bar because we only had US and Agentinian dollars. The flight was more expensive (but - kids under 12, half price, under 5 are free) but extremely convienent. Just a warning - if you get car sick - take the ferry. Poor Ally thew up the entire 15 minute flight!
