Uninteresting place to live (4)
I believe the answer is:
flat
This clue is a double definition.
'uninteresting' is the first definition.
(thesaurus)
'place to live' is the second definition.
(a flat or apartment is a kind of residence)
(Other definitions for flat that I've seen before include "Apartment; plane" , "razed to the ground, having had blow-out" , "Absolutely" , "Not hilly" , "Apartment; even" .)
