...Manchester-  looking to set up a meet with a local lady who is outcall only- any ideas for safe clean and discreet?

Obviously I think you mean incall

If she is really "outcall only" and he's looking to book the hotel room then it's an outcall not an incall.

that is correct- the contact didn't pan out but always open to suggestions for future reference

Pretty much all the major chains are there and not very different.  
Downtown hotels might be easier for her to get to if she does public transport. Also a better option if you are planning to spend the day/ night and want to go out to eat without having to drive/Uber.
If you are planning on Melanie Sugar, bring your own condoms, she seems to forget hers.

They have cock blocker elevators.
