Gustavo's place is within walking distance of the metro (10 min) and 15 min walk to Plaza De Armas which is the most happening place in that area.
We had no trouble checking in and Gustavo made us feel right at home as he walked us through the tidy apartment.
The apartment has very good amenities with a fan to escape the hot Santiago summers, a couch and cable TV, High speed internet (we clocked 300 mbps), clean bed and linens. There are plenty of minimarkets around the block to make use of the well-stocked kitchen
A note on the washer/dryer - The lady managing the laundry said we need to download an app to make the machines work, and that the app is only for Chilean residents, but I didn't verify the authenticity of the statement.
Noise - As with any high-rise building overlooking the freeway, there's bound to be noise, but the windows do a good job of insulating it
I would highly recommend Gustavo's place for anyone looking to tour the bustling city of Santiago.
