I was torn between stay on Av 9 de Julio at the obelisk or Recoleta. Man am I glad I chose CH Recoleta (Cyan Hotels)! After lots of walking in the area of the obelisk, I found it to be loud (cars and car horns) and every bit of big city busyness confines to the sidewalk due to traffic with little green space.
The are around CH Recoleta is completely kick back and casual with people having picnics on the grass in the large green spaces/parks in the area. Steps from the cemetery and less than 5 min walk to lots of other major attractions (Museums & the famous metal Flower). Just steps to hop-on hop-off bus stop (of you two options, the red bus seemed to be a little more efficient than the yellow bus), tons of cafes/restaurants and a decent sized (and very clean) mall. The immediate area of the hotel comes alive at night. Lots of friendly people enjoying an adult beverage, a nice meal & socializing with friends and visitors. I never once felt unsafe in the area, even when walking around at midnight or later.
The hotel: It’s in a very old building (I’m assuming) so there are some areas that look old & dusty. Not many, just here & there. The lobby had controlled access which I liked and was tidy and updated. Staff was great. Patient & helpful. All the employees I talked to (4 people) spoke very good English. I booked the suite side of the hotel (simply because it was a little cheaper-go figure). The room was huge, clean, & comfortable.
Don’t hesitate to book this hotel.
