The yurts are in a beautiful setting, really tucked away from the world. For a group of adult friends, if you hired all 3 yurts together (and if they had different beds in them) it would be great.
We were a party of 7, squeezed into a yurt which would comfortably sleep 4. I really wish the owners had said to me when I enquired about booking that there really wasn't space for 7 of us.
Having stayed in other yurts in Devon, I can tell you these are not luxury yurts as it suggests on the web site. The most unfortunate thing about our stay was the beds. They were soooo uncomfortable. The owners have chosen to buy cheap futons with very thin mattresses, through which we could feel every single wooden slat of the base. I was woken up every time I turned over,by the discomfort. I came home with slight bruising to both hips - not the kind of holiday memories you hope for.
On the plus side....
The compost toilet was fantastic, really loved it. Liked the eco friendly aura of the place too.
What can I say? Get some different beds, stop calling this a luxury yurt holiday, and lower your prices to reflect this. I have paid £100 a night to stay in yurts which were bigger, had more privacy and had fixed, really comfortable beds.
There is potential for these yurts to offer people a great get away, with just a few changes.

This site is for the serious back to nature visitor. we visited with 5 children and stayed in the largest yurt, it was a different experience and the yurt looked nice but would not recommend it for young children. The site prefers visitors without cars but with 5 kids and all the baggage that goes with them this was not an option and unfortunately we had to park away from the yurts and lug all our bags over to the yurt in the rain. Because we arrived after 7pm due to accident on the motorway, we were not greeted by the owners and never saw anyone the whole time we were there. We had only 1 tiny solar powered light and candles, it was hard to unpack and get the kids ready for bed and make up beds in such dim light. The Futon beds were the worst beds I have ever slept on and had an awful 2 nights sleep, you could feel every wooden slat through the mattresses. The compost toilet wasn't as bad as I expected but was abit of a jaunt in the pitch black and wet, we were constantly changing the kids clothes and shoes as the grass is long in the field. You wouldn't know that you were on a farm apart from the sheep in a nearby field but we have been there and done it but won't be doing it again. The only difference to this and proper camping was the fact that you haven'tt got to put your own tent up. Give me my airbed any day ! This should be advertised as not for the faint hearted.
