Great location and really beautiful and interesting building, nicely furnished and equipped. I liked the proper hairdryer (rather than a tiny one attached to the wall) and the comfortable bed, plus individual room air conditioning/heating. If you want a modern hotel, this won't be for you, but if you appreciate history, then you'll enjoy your stay.
Breakfast is ordered from a menu, rather than a buffet. Good value when included in your room price, but rather expensive if you need to purchase separately. Lovely breakfast, other than the coffee, which I didn't enjoy.
Some issues with being charged for the room twice on check in, but was easily resolved the next morning. Also no room key on check in, but again, that got sorted out and delivered to my room very quickly. Lift out of order due to flooding, but I was only on the first floor and have no mobility issues, so no real problem (although it would have been nice if the receptionist had offered to help with one of my bags when he showed me to the room).
All in all, a good comfortable stay, but there are a few things they could improve.
