We highly recommend it during off season. Milos is a beautiful island with much to offer. Christians place is in a great location and the story behind it it's worth to discover. We spend more then a week without car and we were able to walk to every interesting spot. We also used the kayak they have at the property, it was an amazing experience. Just be aware that during off season the whole town is closed besides one little kiosk and a small cafeteria where you can buy the very basics. We felt very welcomed by Christian and Melanie and enjoyed their company and histories a lot.
Be aware, there is a legion of extremely cute cats which are gonna make it very hard for you not wanting to adopt them. The room was very well equipped and comfortable. We hope to come back in the future.
