Its a hard one just like the beds,i know its a personal thing and everyone is different but we had 2 friends stay with me and the wife on the Friday and Saturday and they said the same and even tried moving to another bed and it was the same,we then had 2 family members come from the Sunday to the Friday so no more than 4 adults in the house at any time and again they said the same that the beds are really hard.. As for the house itself it was great nice big seating room plenty of space, lovely views looking over snowdonia,dining room nice big table right next to the kitchen which also is big and very well stocked with pots pans cutlery and china and glassware the only let down was no coffee machine or cafeteria so had to go out and buy one.a nice surprise was the starter pack which was milk,orange juice ,biscuits, kitchen roll and a multi pack of breakfast cereals. There was also 2 toilet rolls in every bath room and clean tabs for the dishwasher and the washing machine aswell. I would recommend this place as it was a very nice stay ,really clean and tidy ,but i would just let people know how hard the beds are
