Got an offer for lse accomodation but idk if I got ensuite or normal single

When I checked on hallpad the room type is single. How do I know if I got a single normal room with shared toilets or a single ensuite? Or is it if its ensuite that it would say single ensuite. Btw the accomodation is bankside. If this is not single ensuite does anyone wanna swap this accomodation for single high Holborn?
thanks
