A sense of place is important whether you're writing fantasy or not. No-one just lives in their head and so the reader has to see/hear/feel/taste/smell what the character does.
Writing without describing place is like giving a reader a play script with no stage directions - a lot of words in a void.
I've said before not to spoonfeed the reader, but you have to give enough so the reader is with you - and then don't change the rules!
Don't, in the first paragraph, describe a sleepy seaside village with images of narrow winding roads and kids playing cricket in the streets and then have your characters driving breakneck down an old industrial road.
Don't make it worse by having your characters escape from the police by hiding in a bat-infested cave on said industrial road and describing vegetation, dust etc but never, ever mentioning a building, factory, workshop or chainlink fence.
Readers live in the real world predominantly through vision and a sense of space. You have to activate their inner eye and have them orientate themselves in the space you create.
Draw a map. Draw the interior of the house/shop/school and then place that house in a street, that street in a town etc. Know for sure where everything is and how to get there. Check back on it if you have to.
This applies to everyday fiction as well as fantasy. Make sure your reader can picture it - not with beautiful, meandering language but concretely with solid images.
