I would avoid this property in the summer. When I stepped into my room it was uncomfortably warm, and upon checking the AC unit I realized why: it had stopped with an "E9" error. And that's when I remembered staying at this same motel before and encountering the same problem in other rooms: the AC unit needs to be turned off and then on again, but will only work for a half-hour before it stops and displays that same E9 error.
I woke up a few times during the night (hard to sleep in such a hot room) to reset the AC unit, but the room was still uncomfortable in the morning. I asked the front desk clerk about it, and she said, "Oh, is it doing that again?" Clearly this is a known issue which has plagued this hotel for *years*, and still isn't fixed.
Avoid during any month you think you might want working AC. And since the same unit controls the heat, I wouldn't be confident it would work in the winter...
