I was a little weary of booking a camper in January but it wasn't a problem at all. The first night I didn't use the little heater as the temperature was perfect when I went to sleep, but woke up being a little chilled. The second night I used the heater, problem solved. I didn't end up using the outdoor shower but would have in the middle of the day, not at night or the morning as it was too cold.
I would definitely stay here again, its cute and easy. I could work and rest in the very tranquil space.
