Absolutely Perfect !
Flawless from the airport pick up until check out. It was our first trip to Buenos Aires and we were undecided between the Park Hyatt, Four Seasons, Alvear Palace and Faena. We were to be in BA twice during the month of September as we were traveling to South Africa from Mexico and decided to book the Park Hyatt for the first leg of the trip and leave the return open so that we could visit the other hotels while in BA. Two minutes after we checked in I already knew we were staying there again. The place is just stunning, it is actually two buildings, the palace and the new wing joined together by an underground art gallery or on top by a beautiful garden. They have blended the old with the modern in a very sutil and luxurious way. We were up graded through AMEX fine hotels and resorts program to a huge one bedroom suite.The staff are very professional and capable, the concierge was great and recommended the best and trendiest restaurants and clubs (don't miss Casa Cruz, Cluny and La Bourgogne). While in BA we visited our other hotel options and I would recommend the Alvear Palace to anyone over 70 , the Faena to absolutely no one (worst staff I have ever met, a shame really because the property is beautiful) and the Four Seasons to business people who will wake up not knowing at which other FS they are at, nice but lacking character.
We obviously decided on the Park Hyatt for our return 3 weeks late and half the staff still remembered our names.
All in all Buenos Aires is a great destination, like being in Europe but at the half price !
Also try the spa after a 10 hour flight its great
