Here’s a polished review-style rewrite:
I had a very disappointing experience. When I arrived, the person handling check-in wasn’t even in the building, and I had to wait 30 minutes just to get inside. There are over 30 capsules, but only two small showers and one bathroom for everyone, which is completely inadequate. The capsule itself was tiny and made noise every time I moved, making it impossible to rest. I would never stay here again.
