Cute idea for an Airbnb but not entirely well executed.
My stay coincided with rainy & cold weather which made the stay very uncomfortable. Host has hot water bottles and a very small fan heater (with a note attached to ask you only use if you absolutely have to) available but this does very little to warm the place. Entire stay was spent shivering in bed.
The bathroom which is under the access stairs to the top level gets really wet and the steps leading up to the sleeping level stay quite slippery. This is dangerous in rainy weather.
The tardis looks to be a home build job that lacks some finishes and doesn’t run very smoothly. The downstairs door is hard to open and close and sliding stairs are difficult too. Check in was difficult due to lockbox having deteriorated over time and is very tricky to open.
This might be a cute overnight stay in spring for a solo traveler who doesn’t mind some discomforts but unfortunately I wouldn’t recommend in cooler months.
I had booked for two nights but had to leave after the first night because it was too unpleasant
