STAY AWAY. The host is so cheap that it hurts the whole experience. He would require you to specify an exact hour for checkin. And if you’re late then you’d need to pay 10 EUR per hour or part of it.
The host will only let you know about several limitations in the house like not using the oven, or power stops if anything else is running in parallel to the AC - he will let you know about it AFTER the booking and payment.
