I stopped by while I was in Santa Fe on the recommendation of friends. I had no reservations, but there was space in the women's bath and I was able to book a yasuragi treatment. I let the desk know it was my first visit, and one of the staff immediately came out to give me a little tour and explain how things worked, so I had no unpleasant surprises or confusion that others seem to have experienced.
The bath was wonderful - yes, there were a bunch of naked ladies, but unlike some reviewers past I don't need my own personal deck throne and so didn't feel deprived while relaxing in the hot bath, waiting for a chair. I was in and out of the hot water several times - it's darned hot! But it feels great. I was called for my treatment a few minutes before it started, and although my therapist (Philip) was all business, I found the massage really relaxing and comfortable. I wasn't watching the clock, so can't comment on the precise number of minutes I got, but it felt like just enough.
Responding to what other people have complained about:
1. People are naked. Yes, that's true. I guess a private bath is necessary if you have a problem being naked or seeing naked people. Didn't bother me at all.
2. Kimonos are thin and winter is cold. That's probably also true, though I got there on a rare warm day in winter (about 45 degrees). I wouldn't spend a lot of time wandering if it were super cold - but from the bath down to my treatment was about 20 steps, I doubt I'd freeze to death.
3. Gift shop isn't luxe. That's true. I was there to have a hot relaxing bath, not buy tchotchkes. But if you wanted to buy things other than lotion or shampoo, I wouldn't recommend the gift shop.
4. Staff is rushed. Sort of true - they didn't waste a lot of time chit-chatting and Philip was certainly ready to move on as soon as my treatment was done, but he didn't shoo me out of the room or anything.
5. Spa is not luxurious enough and guests are not treated like royalty. That's definitely true...I'm not a high-maintenance person, so this wasn't a negative, to me.
6. Stairs are numerous/steep. Yes. I'm in pretty good shape, but I was kind of winded. I guess I should have walked instead of running!
7. Locker rooms are small, showers are small. Yes. I wouldn't have minded a bit more room to change. Winter coats and boots took up a lot of room. But everyone was nice about it.
8. You have to bring your own comb. Seriously? I would anyway...but yes, this is true. The spa assumes you have a comb and does not provide you one.
