An incredibly luxurious castle turned hotel, Hotel Providence was purchased by the Countess of WerdenBerg in the years following Twin X. While it still functions as hotel open to the public, it is entirely staffed by NERV personnel, and an entire wing is reserved for NERV activities.
The Countess has generously offered to provide full room and board for the pilots at this luxurious estate.
Hotel Providence is modeled after the real Oheka Castle, for reference.
More information probably to come.
