The stay at Fernando was very comfortable and perfect to spend time working, going to ECLAC (5 minutes walk), move to downtown, and rest in the evening. Very light room, with good space, enclosed bathroom, and plenty of storage space. Well equipped kitchen. Nice, light, and spacious common place. All very clean and tidy. Fernando was very quick in communicating, made check in and check out extremely easy, and is a nice and friendly host. And, a non-minor detail when you stay in Santiago (in my experience): the flat is very warm, all day around, so perfect to comfortably stay, work, read... My only minor with respect to location is that you are in the middle of heavily traffic roads, which despite the 12th floor can be noisy. If you are not accustomed to noise at night, you may need earplugs.
