It’s a great hotel, in a great location (Calle Florida).
Of course it’s not a modern hotel, but it is very, very comfortable (what a nice bed!), clean and with a very good service. It has a great breakfast and fair rates.
The room was not a very large one, but it was ok and reasonable.
It was a great stay (my wife, two little girls and I) and I would recommend this hotel. I’ll certainly be there again!

To stay at the Plaza Marriott in is to be reminded of the splendor that was Buenos Aires at the turn of the 20th Century, when Argentina was an emerging economic power. Buenos Aires sought to enhance its image as the “Paris of South America” by commissioning the great architects of Europe to fashion its important buildings. The Plaza Hotel and Teatro Colon were opened in the same year (1909) and remain visible manifestations of the best money could buy back in the day.

While the Plaza has been thoroughly updated and modernized over the years and these days is managed by Marriott Corporation, this grand dame of BA hotels retains much of its original character, charm and opulence. Rooms feature modern conveniences alongside original architectural detail—Wide moldings and coffee makers; floor to ceiling windows overlooking Plaza San Martin alongside luxurious sheets made from high thread count Egyptian cotton; hand painted murals and lavish use of woods and marble in public areas alongside the most extensive work out room with the most modern equipment of any hotel in Buenos Aires; and the list goes on.

While there is not a single employee employed today that can remember when the hotel first opened, several members of the staff have been employed at the Plaza their entire adult lives, some going back 40 to 45 years. Service here is flawless. I broke a glass in the middle of the night. Glass shards were on the floor and some landed on the bed. I phoned downstairs to report my misdeed. Within four minutes the maid arrived and spent the next 30 minutes changing my bedding, vacuuming the floor, replacing the glass, and offering an apology that the first glass had been made from such thin material that it would break.

I have read reviews of this hotel for several years. In the midst of the numerous compliments there have been a few complaints about long lines at the breakfast room, guest rooms past their prime and rude staff. This is a hotel that listens and responds to complaints—now a days when the breakfast room reaches 80% capacity, the Plaza Grill (normally not open for breakfast) is pressed into service for breakfast; all rooms have been redone within the past five years

Each room at the Plaza is unique. I stayed in two rooms-398 and 722. Both had been lovingly and recently refurbished but differed in many ways. The third floor room was small and the bathroom was smaller. It was a nice room with a great view, but without a lot of moving around space. 722 was huge—windows on two sides, overlooking Florida Street and Plaza San Martin. The bath had double sinks and was about the same size as my first room on the third floor.

Stay at the Plaza Marriott if you are looking for a convenient location in downtown Buenos Aires and you find enjoyment in old world charm with a touch of luxury.

This was my first stay at the Plaza in close to 20 trips to Buenos Aires. It will not be my last.

this hotel was convenient and great. had a Jr. Suite which had ample room and was quite comfortable. Room was kept impeccably clean with new towels and linens daily.
the Executive Lounge is a great place to meet people.
the Fitness Center is excellent with friendly staff .

I think the breakfast buffet (included) was a bit disorganized and chaotic at times.

Although I did not try it, a local told me after checking out and were at the airport, that the upscale hotel restaurant serves the best steaks in buenos aires!

I would stay there again without hesitation.

Stayed here sometime ago but it was a nice hotel. Service as far as i remember was spotty (we got in BA from an overnight flight from Santiago, Chile and had to wait in the bar till lunchtime for the room) luckily the hotel is located at the end of Florida, a pedestrianized shopping road (with many public tango dancing couples and the beautiful Pacifico Mall). Breakfast was ok but i guess what made the wait for the room bearable, was the room they gave us, it was a slightly bigger room (though the loos were a bit on the tiny side) with a nice balcony overlooking the tree lined plaza in front of the hotel, just right to sing "dont cry for me..." its also a nice walk to recolleta (though its a bit far, florida would be enough.. shopping shopping shopping)
