Good apartment. Really comfy. Not luxury (dont expect anything like that for the price) but warm enough. You may call it home.
It's near downtown area, you can walk to the subway or if you want yoi can walk around 20 min. To get into downtown.
If you want to have a good time, you may want to consider to go to santa isabel street, it has plenty of restaurants and coffee shops.
Great communication from the owner of the apartment, he will reply immediately at any moment, to help you out with anything related to the apartment.
Hopefully, whenever i have to return to Santiago i will look for this Airbnb
