The first thing to say is that the numerical ratings I have assigned are meaningless. Our visit to Texas took place under unusual circumstances (a sudden plunge in the temperature). The problems we encountered may be completely atypical.
To provide more details is impossible in the space provided. I have written a detailed review, which I would be prepared to share. Here's a brief synopsis:
There was virtually no hot water in the bathroom throughout our stay.
Internet was out for 48 hours.
The "duplicate key" didn't fit the lock.
The cooking implements in the kitchen are inadequate.
The entryway is uneven, steep, and pitch black at night. Would not be suitable for people who are unsteady on their legs.
Jonathan's responsiveness varied. He was great at check-in, slow initially in responding to our problems (he was out of town, and had provided no back-up host), and, once he appreciated the situation, both concerned and fair-minded. We received a partial refund.
