Uninteresting accommodation? (4)
I believe the answer is:
flat
This clue is a double definition.
'uninteresting' is the first definition.
(thesaurus)
'accommodation?' is the second definition.
(type of residence)
(Other definitions for flat that I've seen before include "unexciting" , "Pressing implement" , "Level - below the natural note" , "without qualification" , "Featureless" .)
