It's not in a place it could reach me from. I live in an apartment building and a locked door separates my apartment from the staircase.

As for identification, I think it belongs to a species called brown long-eared bat. They are relatively common in the country.

Edit: it looks more grey than brown and might be the grey long-eared bat that was never seen in the country before, despite living just south of here. I might have to send the photo to the National Bat Preservation society later today.
