Speaking as a guy (and maybe more than 50% of Conrad guests are guys) this is a great idea. Shaving foam and aftershave cream are great amenities.
I just stayed at the Conrad Algarve and tried the Shanghai Tang brand for something different from the Aroma Therapy that seems to be their standard. It's not a BIG DEAL with me but I found that I preferred the Shanghai Tang. Tea scented soap!!!
I used the Conrad app to pre-order the ST amenities and they noted it on arrival and sent up a member of the housekeeping staff after I arrived to change out what was in the room. That was very nice.
