Amazing location! We didn't have a clue we were going to drive up a mountain and stay next to a "castle"! The hotel is fantastic...it looks modern enough with renovations to pass for a somewhat swanky hotel, but the rooms inside are very charming and homey. We were on the top floor and had a view of the trees and off into the distance. We were totally enchanted.
After checking in we went over and explored the palace and castle remains. There's a restaurant over there that overlooks the valley below with insane views, but it wasn't open. I don't even know how people know to come eat here it's so hidden! The restaurant attached to the hotel was booked, so we didn't eat there, but it looked pretty amazing. The free breakfast buffet was fantastic! And the staff is incredible attentive. They're really, really nice (and speak English). We had a problem with our tv, and this very nice woman came right up to help us. The wifi is a little shoddy, but that's ok. We really, really enjoyed our night here and would stay again if we ever decided to go back to Hameln.
