Carolina's place is in a good location in Providencia, on the 20th floor of a high rise apartment building.
Carolina wasn't around for most of my stay, but when she was there, she was very friendly, offering local tips, and even letting me know that I could use her bicycle if I wanted. She was very quick to respond to any messages I sent her, both before and during my stay.
The place itself wasn't as big as it looked in the pictures, but the size of the room was totally sufficient. There was a nice desk/table with a comfortable chair for working on your laptop. You have your own bathroom (across the hall). It is very small, but has a nice full length mirror.
The listing does say that smoking is allowed, but does not mention that the host smokes in the place, so I was surprised to see that she was smoking in the living room while I was there (only on one occasion). Since no other reviews mentioned this, maybe it is not a common occurrence. But if you do not like cigarette smoke, this may not be the place for you, or at least you may want to check with Carolina to clarify.
The listing says that breakfast is included. But this just meant that you can take whatever food you can find in the kitchen. It was more like you can make yourself at home, including in the refrigerator and kitchen cabinets. But there was no breakfast served.
As other reviewers have mentioned, there is some street noise. I arrived during the afternoon rush hour, and there was a lot of beeping and loud buses going by. But there was much less noise during the late night and morning hours. There was also a fan in the room that I used to help drown out the street noise, so it wasn't a problem at all.
