Where should my friend meet us off the ship at Buenos Aires?

As we have a full day and a night at Buenos Aires before disembarking, a friend is coming to meet us to show us the city.

Can anybody familiar with the cruise dock tell me where he should go to meet us from the ship?

I would be curious to know this also, arriving on Celebrity Infinity January 20, 2018.

The terminal is a zoo. Hop in a metered taxi and go to the nearby Sheraton Hotel in Retiro. Meet at the bar. Caveat: the taxis that work the cruise terminal are a gang of thieves who always try to overcharge by using fixed fees. Don't accept that. Inasmuch as you won't have bags, just cross the street, walk down a bit either way and hail a street cab. Tipping is neither required nor expected. Should not cost more than the equivalent of $5-7.

In the end we arranged to meet at the Hilton. Some taxi drivers were only interested in people looking to do a tour. I'm English/Spanish bilingual and ended up with 2 drivers both wanting to take us to the Hilton for US$10.

Our friends were able to pick us up right at the Port Terminal. An alternate good place would be at the Sheraton.
