My husband and I stayed for three nights.
The location of the B and B is wonderful. You are surrounded by trees and when you look out from the balcony at the top of the property it gives you a feeling that you are in a tree house.
There are tea and coffee making facilities in the communal lounge, soft drinks and biscuits. The breakfasts were good. Make sure that you eat before getting to the B and B as there is nothing local that you can walk to and the nearest restaurant is about 30 minutes drive away. This is not surprising as you are staying in a park.
The rooms were spotless and even had a rucksack in the wardrobe to use when you are walking together with a lots laminated maps for the local area.
Karen who owns the B and B was brilliant at advising us where to walk, things to do and where to eat and this certainly helped us have a wonderful time in Yosemite. She even gave us water bottles as we did not have enough.
We would recommend a stay here to anyone.
