As an astrophotographer who has been to Terlingua/Big Bend several times, this property was excellent. Remote and secluded from other people and light intrusion. For reference we stayed in June 2021. Other reviews mentioned bad smelling water and other inconveniences. We did not experience that. The tap water was fine for showering and washing dishes, probably drinking too, but since the owners provided ample bottled gallons of water we availed ourselves of that convenience.
We used both the main house and the Casita. Other reviews complain about the distance/terrain to reach the Casita. Yes, it is farther and steeper than most people will want to walk, but if you're into hiking you can do it. However, it is easily drivable in an SUV or Truck, you don't need a 4X4. I would not recommend driving in an average sedan, but if you're careful it can be done. The drive up has large gravel and is quite bumpy, which may be uncomfortable in a standard passenger car. But because we read the details of the property before booking, have a truck, and understand what we're getting, it was no problem for us.
If you are booking this property, or any property in Terlingua, understand that you coming to a remote desert climate. Conveniences are hard to come by, however this property is close to the Terlingua Ranch Lodge where you can find a restaurant, ice, and a pool (for a fee $8.50pp/day-Children under certain ages may be free).
Sunsets at this property are amazing! If you're booking a stay here, book during a new moon for the most brilliant skies and view of the Milky Way. We observed lots of wildlife on the property including deer, coyotes, and even a rattlesnake (yes you need to used caution out here).
As the details state, there is not central A/C in the casita, it is a two room house with a Kitchenette/Living space and 1 bedroom. When we arrived there was only a wall mounted AC in the living space which was not cooling the bedroom. However, as soon as I informed the owners that there was not sufficient cooling in the bedroom they had a maintenance person out within a few hours and installed a window unit. The space was immediately improved and we were comfortable for the rest of our stay. I was really quite surprised at the speed of the resolution. If you have any issue, they are extremely responsive. We're already considering our next trip to Terlingua and CDR is at the top of the list.
A great property if you want remote, peace and quiet.
