Jean's place is very nice, just like the photos and the bell men are very friendly too. I would not recommend this place to anyone who does not have someone who is fluent in Spanish with them. The neighborhood/markets are generally unfriendly toward foreigners.
It's about 20 minutes or so from Las Condes, the most friendly area toward foreigners which is very nice to have so close.
I would say that "sleeps 4" is a bit of a stretch (I brought 4). 2-3 seems more reasonable.
Claudia, Jean's mother, was extremely welcoming and made us feel safe as guests.
If you have a car larger than a small sedan, it will be very difficult to park in the designated stall, though still possible. We parked a Nissan truck but it was not easy.
Overall, we are grateful for what we received at such incredible value. Thank you Jean and Claudia!
