The Spanish support fashionable place to stay (5)
I believe the answer is:
hotel
'place to stay' is the definition.
(somewhere to stay as a guest)
'the spanish support fashionable' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'support' is a charade indicator (letters next to each other) (in a down clue, some letters hold others up).
'fashionable' becomes 'hot' (I've seen this in another clue).
'el' after 'hot' is 'HOTEL'.
(Other definitions for hotel that I've seen before include "Accommodation for travellers" , "Lodging establishment" , "Large guest house" , "Where one may stay" , "pension?" .)
