Good as gold.
The apartment is fantastic, humble and stylish at same time. The bedroom with private bathroom is very nice — great double bed, furniture for our stuff, large TV screen and very comfy. Kitchen is super complete as well, with all utensils you may need.
The neighborhood is quiet (in the sleeping hours) and Ñuñoa Plaza is the best place in Santiago for you to stay. Its a new and modern part of the city with the newest metro station line at the time (did start working in February 2019) — Chile España station — just 1 block away of the apartment.
Luis place is near of a big supermarket (LIDER, avoid UniMarc!) and, if you like night life, Ñuñoa Plaza is your place. Our advice is to spend your day exploring the touristic parts of the city and, when you come back home, you will have a TON of bars and restaurants of all time VERY, VERY near to your place, Luis apartment, for that happy hour or good moments with beer and drinks.
Departing from Plaza Ñuñoa you can reach every part of town on a super easy way, since Santiago's Metro system works super nice. If you need more tips or info, just write me a private message and I will be happy to help. For example — for those who want to go to the marvelous El Yeso Dam (Embalse), do it by RENTING a CAR (if summer there). Super simple, I can teach the way we did departing right from Luis house. The same for Val Paraiso and Viña del Mar.
Well, to sum up things:
— The location of the apartment is perfect, easy to get relaxed after a busy day sightseeing with nice bars and restaurants very, really very near where you will be staying
— The neighborhood is fantastic and completely safe. You can walk peacefully after midnight with absolutely no worries at all!
— The apartment has everything you will need, be sure of that. You can wash your laundry, cook your meals and keep you food and drinks on the refrigerator! Loved it on every way!
— Luis is a very lovely person. It was wonderful to meet and to talk to him, even since he is not fluent in English. He rarely stays at the apartment, so you will have a private stay most of the time.
