We went after booking tickets online, but you can probably just pay at the door as there is not a queue at this Museum. It's not open every day so best check beforehand There's a stunning medieval courtyard and a series of rooms with all kinds of collections. Unfortunately after about 2 hours we were exhausted and tired, there is not place to sit in any of the rooms. The only seating area is in the courtyard and that's very limited, so it's hard to take a breather, recharge then continue. The Michelangelo Room is closed at present.
