Location is really good, parking excellent, enough toiletries, and kitchen items. The only missing items for my comfort were laundry soap and coffee :) but there were many many other items so in that respect you should be good.
No coffee maker though, but you can manage with old school brewing and double
decantation. Washing machine works fine, but it can also work as a dryer and that functionality fails after 30 minutes of the 90 minutes of estimated running time.
We had issues with heating and after some workarounds provided by the host and me, we could manage. I hope thoroughly testing and diagnosis has been done after my staying.
So here is that I suggest both the guests and host to work in advance in the issues reported by other reviewers to see if they have been addressed.
In general, I think this place is for advanced guests because some details are really tricky and require either experience or patience to figure out how stuff works. For example, the checking process is documented with accuracy and thus you really need to read carefully and follow step by step.
