We stayed at Cecilia’s apartment for over a month, and the experience was really great.
The place is big and super comfortable, and it includes all the perks that we were expecting: modern appliances (even dishwasher, not so common in Buenos Aires), comfy beds, work area, high speed wifi, parking spot, and more. The location is awesome, with lots of options for mobility, food, coffee, or just walking and wandering around.
Also, Cecilia is a superb host, she was super responsive and went out of his way to help us multiple times, even though she was traveling.
I’d definitely recommend staying here!
