Spent two nights here and enjoyed Engelberg a great deal. This is a good, basic hotel. Staff were all exceptionally friendly and helpful and the room and hotel were fine. I loved the water pressure in the very bright bathroom. More bathrooms don't have sufficient light, but this one sure did! There was also a fridge in the room, which was nice. Breakfast was basic - boiled eggs, some breads, yogurt, fruit salad, some cheese and meats. They also had a smoothie of the day.
The hotel is very centrally located, but rooms in the front are very noisy, since it's on the main walking street.
