We three adults used the house as a home base for our explorations of the Guadalupe Mountains NP and Carlsbad Caverns. The house was as advertised, clean, well appointed and easy to access. In my opinion it actually had more amenities than advertised as the house was equipped with Direct-TV with an HBO account. The house is located in a quiet residential area of Carlsbad. The owner was attentive before and after our stay but did not bother us during. I'm sure she would have been readily available if needed. We had one very minor issue with the drain being slow in the guest bathroom. We informed Adrian when we left and I am sure it has been fixed by now.
One improvement we would suggest is to upgrade the master bedroom bed to a king size with a less noisy box spring. This is a minor issue but when you are used to a king size bed it is hard to adjust down.
