It's a lovely hotel in a historic house in an excellent location, however there are some shortcomings. Wi-fi was very slow on the third floor, the air con was leaky and made dripping sounds at night, and it would be good to have USB charging points as you would find in most hotels nowadays.
The biggest disappointment was being charged an extra 10 euros per night on checkout, without prior notice, for an extra bed for my son, even though we had specifically booked and paid for a 3 person room. They explained that the bed is additional to the basic price of the room, however it really should have been included; this very much felt like a hidden charge, and makes comparing hotel prices impossible.
