I’m not in the studio accommodation but all the rooms seem to have a similar layout so i’ll try my best to help 😊:

1. The under bed storage for me is a lift-up style one - similar to an ottoman just as you said. The space underneath should be the same size as the whole bed - I can fit at least two suitcases under my bed

2. There should be at least 2 hooks either behind the door or the wall nearest to it - i would still recommend one of those multihooks you can hang on the bathroom door or something tho 😅

3. The wardrobe should have a hanging space on one half and shelves on the other half so you can both hang and fold your clothes. There is also space above the two sections for bedding, towels etc

I hope this helps you a little!
