We stayed in Ehi's back garden accommodation during a cold spell. So make sure you take his advice and inform him when you'd like the heating on, as its controlled by timer from his house and not by you.
The main bedroom has a double bed with thin duvet and a couple of spare blankets. Next to it is the fridge, so I left it switched off to make sure it didn't disturb my sleep. The bathroom is small but good. Plenty of hot water in the shower. Would stay again
