How to book in Toms hotel?

[Woofsoon]

Hello, I’m planning a trip to Berlin in April. I’m thinking to to Toms hotel instead of axel hotel but I don’t know how to book. It doesn’t matter what website I try, it’s always the same:

No rooms is available

 any clues?

This hotel is closed - permanently.
