We are a family of 4 with an 8 and 10 yo and we comfortably fit in the apartment. Casa Sofia is located directly on the caldera with an uninterrupted view of the water. It is truly magical. The public path is behind the apartment so we were not bothered by other tourists walking by. As with all the cave houses, you will need to be fairly fit to get up and down the steps between the different sites, shopping and restaurants. Envious of all your neighbors with pools? Don’t be! There is a hose on the veranda and when we got too hot, we simply hosed down- it was perfectly refreshing. We thought 2 nights and about 48 hours was the perfect length of time to experience the sites- an easy layover between Crete and Paros.
