The pictures don't lie! This house was a great place for my husband and I to stay on Serifos for 5 nights. The kitchen is fully equipped (even had spices), living rooms both inside and out are very pleasant to enjoy your time while not at the beach or exploring the island. Bonus--The beds are comfortable (first and last time we experienced this in Greece)!
Karlos arranged for us to be brought from the ferry to the house so we didn't even have to find it ourselves. It's in very close walking distance to the big beach and to the town where groceries, restaurants, anything you need can be found.
We would definitely recommend people stay here. If we ever return to Serifos we'll be back. It was a treat!
