As everyone has said, the view is quite literally unparalleled and the property is wonderfully cosy. I stayed just one night with my kids (ages 15, 12 and 3) for a quick pre-Christmas getaway and we all really enjoyed our time onsite. The property was perfectly clean and warm, the permanent beds comfortable, and we all felt immediately at home. The host had generously left some snacks and selection boxes, which were appreciated, and we all loved the quirky personality of the place.
As far as check-in, the instructions via the app simply said "other". From this I thought perhaps someone would be there to greet us, but when we arrived at 3pm no one (other than the neighbour's super sweet dog) was seen. We eventually found the key and let ourselves in but the only contact we had from the host or anyone else was a msg sent after 9pm hoping that we were OK.
My 3 yr old stayed on the foldaway bed, but I don't think it would support a larger/older person due to broken supports. Also, although there were a heap of large blankets in the cupboards, I wasn't able to find any sheets or pillowcases for the foldaway bed.
I was planning to make a dinner and do some small baking, and so I was glad that I'd brought all supplies (milk, butter, sugar, etc) with me as none were provided. I hadn't brought coffee as the advert mentioned a coffee pot was included, but unfortunately I wasn't able to find coffee anywhere (although there was some tea).
All in all, though, our experience was very positive and we would be absolutely delighted to stay there again.
