The house is as beautiful as you see in the pictures. I would recommend coming before mid-October because the towns only restaurant closes then for the winter and there is nowhere else to eat in easy walking distance for an evening meal.
The host family was amazing and very accommodating. There was wine, fresh fruit, and juice waiting for us. Milos accommadations was quickly responsive to any questions/requests including having food delivered the first night when the restaurant was closed for the evening already (it had been its last night)
I would recommend a car as the island has lots of hills and prickly brush so you can’t easy cut across the island by foot cross country. Walking is not a pleasant experience, even in the relative cool of October.
Go to Sarakiniko beach for certain. 20 minutes if you walk along coast. 45 if you walk along the roads. <10 minute drive. If was amazing and very unique
