I stayed more than a month and the host was so kind and had fast feedbacks always. The apartment has excellent location(near the big supermarket, Arauco park, Arauco mall, etc) and you can go any place by walk in 10 minutes.
The part that needs improvement is that the facilities inside the house are old or worn out and there are some parts that need repair, and it is quite hot in the summer because it is the top floor of the apartment. It felt like a rather big drawback to me, and I hope that this part will be improved later.
