From memory the room I had did have a safe in the cupboard. The hotel can confirm on a room by room basis I'm sure.
From memory the room we had did have one in the cupboard. The hotel might be able to advise as to availability in each room perhaps.
I did not ask for one, there may have been.
Sorry I can't be more specific.
Suggest you e mail the hotel direct.
Yes, there is a room safe, but you have to ask for it in the reception. I didn't have to pay anything more for it.
Do not think so.
There are safes in each room, but you must ask reception, and they will issue you with a safe key to activate the safe.
