This room/flat has NO storage room at all.
There is 1 closet but is absolutely full of the owners belongings and if you ask him to please empty it for you to store your belongings, he will say 'no'.
There is no space under the bed either. No drawers. You will need to keep your belongings in your luggage and also to keep it closed and standing because there is not enough space in the room to open it.
