My mum and I rented the cabin while visiting Bristol to meet the new baby in the family. Perfectly situated for us and nowhere near the new Clean Air Zone.
Despite freezing weather the cabin was cosy and warm with an oil fired radiator. Both of were very impressed with the set up. My mum uses a walking stick and was able to access the property, but do be aware that there are steps involved in the access including quite a large step down into the garden.
The cabin was very clean and comfortable. Wifi was good. Communication was clear with specific info regarding how the cabin worked.
We were there in a very, very cold snap and the pipes to the cabin froze on the second night. Merlin brought us water for morning coffee. I bought 15ltrs of water home with me that night (I've lived off grid before) to make sure we could drink and flush the toilet.
I would happily rebook this property in similar circumstances.
