We have stayed at a few places near Felton and this was by far the best. The view was amazing and the location was perfect. There are plenty of beds and room to stretch out. We were out and about most of the time so we didn't need a kitchen. It was raining and we had plenty of blankets. The space was clean and the shower was nice. Dave was very responsive. I had a hard time working the door and burnt popcorn one day and he was quick to check on us but we also had enough privacy to really enjoy our time.
A couple things to note: It is a kitchenette so there is no sink and no place to cook except a microwave. Drinking water, tea, coffee and hot cereal were provided. There were paper goods and napkins which were helpful. Also, the space is under the main house so you can hear people moving above and I am guessing they can hear us although we kept the quiet hours. There is a sound machine but if that type of stuff bothers you it is good to take note.
I would recommend they stay. We would come back.
