Anyone claiming to have a dedicated workspace can easily include a picture of it. Those 99.9% that don't do that can easily be discounted as liars. And if they are lying about having a workspace, well they can just as easily be lying about everything else too - such as:

The place is very quiet (except for dogs, nusiance neighbours and constant building work). Is walking distance to the beach (if you consider a 5 mile treck nothing but a stroll). Has nice views of the park (if you stand on the 5th rung of a step ladder). Has fast internet (provided the local bar has not changed the password recently). Etc, etc
