I’d say trust your instincts. Profile is obviously written by a native English speaker, so it’s an agency. AW profile is 7 months old, but zero feedback. Overpriced for an unknown, unreviewed possible b&s. Just my thoughts.
Sorry, mispost due to unfamiliarity with this forum. This was supposed to be an edit of the previous post
Will you use a hotel or your own home?
Hotel, always ...why????
Probably safety reasons.
If you've got it paid by your business, you could try with the usual strategies (check the whore via the hotel bar/reception) before meeting her etcIf you pay from your own pocket, you may be putting £100 or £200 of hotel cost down the drain if she's not what you expect.
£170/hour is a lot to pay for an unknown.
