Lucho was an amazing host. He communicated very well leading up to my trip, including giving me many recommendations of things to do in surrounding areas before I even arrived in Santiago. The check in process was seamless, setting me up with a key and parking spot (as I had a car) as soon as I arrived.
The apartment is great, with ample space in the living room and kitchen to relax. The room is nice, with plenty of storage for your bags and 2 comfortable bunk beds. Access in and out of the building is easy via a key fob, and the location is prime, close to the metro and walking distance from many bars and restaurants (Bella Vista is close). There is also a pool. My favorite part of the place was the balcony. Amazing views over the city from the 26th floor, with a stellar backdrop of the Andes.
Lucho is a fantastic person and I plan to stay in contact with him. If you are interested in exploring the mountains around Santiago, talk to Lucho first. He's full of useful information and leads treks all the time.
I would 100% recommend staying with Lucho to anyone visiting Santiago.
