Depends what you are expecting

If you are after a great legit massage - don't go.
If you are after any extras - don't go.
Don't wish to be disparaging in any way however the facts are:
1. New shop (couple of months) - shop is a real stretch. Its an old takeaway with a reception and commercial kitchen, and a massage table in the middle of a large room to the side. It's basic and needs a lot of work to make it nice but that said I've seen worse.
2. Older lady (50s?) who has not long completed a massage course in the UK.
3. Messaging - she was very quick to make sure I understood no extras on offer.
My opinion:
Lovely friendly lady but poor massage that warmed up a bit, however inexperience shone through.
Did have an armpit massage which was a first though

She's seems a lot older than her public photograph but is slim, trim and petite.
Perhaps in a few months time things may change once she realises the footfall isn't great in Buxton and the rent still needs paying.
Personally, I wouldn't return even if she did change, but only because there are better ways to spend the £45.
So for your weekend, which was the question asked, my personal view would be get a Thai to come to you to save travelling.
There is one who advertises on Gumtree in Clay Cross and I know she comes to Buxton to meet clients and does do weekends despite what her ad may say.

HTH.
