Hotel, even more attractive (8)
I believe the answer is:
handsome
'attractive' is the definition.
(I know that handsome is a more specific form of the attribute attractive)
'hotel even more' is the wordplay.
I cannot really understand how this works, but
'hotel' could be 'h' (phonetic alphabet: alpha, bravo, charlie etc.) and 'h' is found within the answer.
'more' could be 'm' and 'm' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for handsome that I've seen before include "Nomads he found to be good-looking" , "Attractive in a strong, imposing way" , "Fine-looking" , "Pleasing in appearance" , "Attractive, liberal" .)
