Billy’s house is charming and simple. It is as you see in the pictures.
I would just specify that they are no doors to close off the bedroom upstairs or in the basement.
As noted the patio area is shared with 2 other rental houses so the ambiance depends on who your neighbors are.
The private terrace upstairs off the bedroom is lovely for star gazing at night.
Lachania is a great location to escape the tourist crowds. We loved the Platanos Taverna across the street.
