Buying an AC for bedroom — Tokyo Apartment

Hi all, I need to install an air conditioning unit in the bedroom of my apartment. I was thinking of going the route of a space cooler like this off Amazon Amazon space cooler has anyone had any experience with using these to cool a bedroom? If they're not worth it an I go the route of a more `traditional` ac unit from BIC or similar like these Bic Camera `room` air conditioners I'm assuming that installation would be done by them, is that a correct assumption?

Thanks for any help
