Great location in Bellavista. Well - it has a lot of clubs around and it more artisitic and colorful than other Santiago neighborhoods. Easy to walk to public transpo - guess you can take an Uber too if you want :\
The apartment is clean and super cute and has some quirky items/art/books that expose the owner's own bohemianism :).
Guille is very friendly communicative and thinks ahead about your needs like earplugs for the clubby area in which the apartment is situated etc.
If you need to do laundry, ask Guille, there's one on the same floor. It's not expensive, but you'll need coins.
Definitely staying there again WHEN I am back in Santiago.
