Featureless place to live (4)
I believe the answer is:
flat
This clue is a double definition.
'featureless' is the first definition.
(I've seen this in another clue)
'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; even" , "Digs perhaps" , "Not hilly" , "Lacking interest" , "unexciting" .)
