100 for the hour in Coventry whereas it's 120 in Birmingham. Might be worth knowing.
First time I’ve seen a Birmingham premium being added to a WG’s price however it may be worth a visit for the cheaper rate. She is ok service wise.
But to answer your question I’m not sure, if she was in Birmingham then 100% yes you would have to go through maid but as she is now in Coventry it may be a different maid or same one or she may answer the phone herself.
My feeling is yes you would as mostl likely the maid lives away from the WG’s working flats so communicates via phone therefore wouldn’t matter where the WG is as the booking process would be the same.
