My wife and I stayed in Nico's home for a total of five weeks on a working vacation.
Nico's home is located in a slightly gritty but very safe neighborhood, with a lot of character (the president lives up the block so there is a continuous police presence). It is ideal for anybody wanting a real "local" experience. It is 2-3 miles away from the more popular areas of Santiago like Belles Artes, Barrio Italia, etc., but it has pretty much everything you need within a short walk. There are several great cafes nearby with Wifi to work from, as well as two good vegetarian restaurants about 100 feet up the street. The Quinta Normal metro stop is located a few blocks away along with the Parque de la Familia, a large park that is great for strolling, picnicing, and short runs. There is a fantastic farmer's market on Sundays and Thursdays a few blocks away as well. Parque de los Reyes is about a mile away and is excellent for longer runs.
The home itself is very large with one huge room on the ground floor containing the kitchen and lounge areas; the equally large bedroom is above that and is where the working space is located. It has many windows and a large skylight, so the room is very bright. The rooftop deck provides an amazing view of the city and Andes mountains, and is ideal for watching the sun go down. The wifi is strong enough for a Zoom call while another person is online, but we found that two simultaneous Zoom calls was sometimes a problem if the camera feature was used on both computers. A cleaning person also came once per week which we greatly appreciated.
Nico was very communicative and helpful throughout the process. In anticipation of the cold weather, he ensured we had an electric blanket and space heaters to use. When there was a minor pumbling issue, he immediately sent somebody over to fix it. He also purchased a second office chair so my wife and I could both work from the large desk. Nico was very flexible in allowing us to check out later in the day since we have a night time flight out of Santiago.
All in all, we thoroughly enjoyed our stay and greatly appreciated having Nico as our host.
