I stayed in the red apartment for 3 nights with my husband and 1-year-old son in June. We really enjoyed our stay.
The house itself is beutiful, renovated old building right by the beach. It is surrounded by garden and it's really quiet during night.
The red apartment consists of a bedroom, a kitchen and a bathroom and has two patios. It is well equipped for a holiday and suitable for small children as well. It's not as nicely decorated as the other two apartments, but the two patios, especially the sea view, are a definite perk compared to the other apartments.
The location is wonderful. It's right by the beach: you open the gate and your on the beach. The beach is fine sand and shallow, so it's perfect for children. The house is a walking distance from Scala dei Turcchi, but you need a car to get to Porto Empedocle (to supermarket&restaurants).
We didn't meet Marco, but Gabriella was there to meet and welcome us. She lives in the house herself so it was easy to get in touch with her. She was very friendly, helpful and hospitable.
I would warmly recommend Marco's place to others.
