Location: Incredibly central, couldn't be better. As a solo female traveller, I felt safe walking around at night.
Airbnb: It is exactly as it is in the pictures. Very beautifully done up, it's a stylish unit. It was also incredibly clean. The bed is the most comfortable I've had travelling around LATAM. Do note that if you're a light sleeper, because of the location (and as it's an older building); it would be wise to bring earplugs.
Host: excellent communication with the host. Alejandro is flexible, quick to reply, very understanding and empathetic. He's a solution oriented host which I really appreciated. I had a tough time getting in touch with Airbnb, and he went above and beyond to make sure I got attended to. Definitely a stand-up guy.
