Guillermo's apartment is very warm and cozy. He's a very friendly person and easy to communicate with. I did however ran into a few issues upon my arrival that I want to mention in this review. When I got there there was a very strong cigarette smell, like the previous guest had smoked inside the apartment (I don't smoke).
The smell was still there by the time I checked out. There was a dirty mop in the kitchen sink that I hat to clean when I got there, the bed sheets and towels were stained that Guillermo quickly replaced them after I told him, but most of all none of the kitchen stoves were working so I wasn't able to cook during my whole stay at Guillermo's apartment, and this of course represented me a lot of money eating out. Since I wasn't able to cook, I had to order for delivery, but not many restaurants deliver there, is just sushi and the places from Patio Bellavista.
The apartment is located in barrio Bellavista, a very bohemian neighborhood in Santiago, there are plenty of restaurants and bars around, but if you're looking for a quiet place to stay, this might not be the right one. Friendly 24/7 staff.
Good laundry facilities and small nice gym.
