Have a feeling it’s a pholcidae (daddy long leg) but I’m not sure
Hi. That is a good feeling you have. Looks like it might be a gravid Pholcus phalangioides.
There are a number of other similar cellar spiders, the long bodied one of the most common house spiders known.
Welcome to the site.
You must be right because this is right by the cellar.
LOL, well, I have one under the bathroom sink, another next to the refrigerator in the kitchen,and another just outside the door in an enclose porch.
I have a different sort called marbled cellar spiders out in planter boxes, they seem to prefer outside.
