We had a lovely stay — the setting is beautiful, the dome is cosy, and the host was incredibly responsive and kind, even bringing extra firewood late in the evening!
The only issues were the uncovered see‑through section of our dome, which let in the sunrise very early (no curtains to cover the sun), and the curtains not fully covering the sides of the transparent parts meaning it was difficult to get changed at times.
We also had a small disturbance from neighbouring guests on the first night.
The outside could use a jet wash. But not off-putting.
I would highly recommended asking for the hot tub to be a over 35 degrees (the hosts offered we didn't take them up in the offer - we should have). Once the hot tub was hot enough we had a lovely stay!
We really enjoyed our stay and would happily return, just with something to cover the top of the dome next time.
