This is exactly what we were hoping for and it even surpassed our expectations. The cabin has everything you need- grill, cooking utensils, etc. All we had to bring was the food. We had only two people and one dog, but there was an extra room with bunk beds so it would have fit a family just fine.
Very dog friendly. Ours had a blast running around the property- which was the perfect amount of room for her to run around. The owner is extremely friendly and helpful- she recommended a few wineries and we were able to bring the dog and enjoy a great afternoon- all within about 3 miles of the cabin. No cell service or wifi but it was actually really great not to have those distractions. Deck in front is perfect- plenty of room, big table with an umbrella that provided a great amount of shade, hammock. Just a really great setting and only 1.5 hours from DC. Highly recommend!
