Charming little critters, aren't they?!
There are lots of Hemidactylus species; I wouldn't like to say definitively which one yours is (the easy guess is Hemidactylus turcicus, the Turkish gecko).
We have one that lives in the electric box by the front door - nice and close to the outside light. But in May-June+ we get lots of mayflies there and he seems to take no notice
Maybe he is sick of them (no they are not just the shed skins).
We have others round and about. They do call - a sort of 'cack', but not very often.
