The view is absolutely gorgeous! Getting down to the cave house could be potentially difficult for those with mobility issues as it does require a lot of steps. However, it's only a short climb up to the main street in Oia and the house is maybe 5-10 walk minutes from the bus station so it's a nice place to stay if you're looking to take day trips or explore other parts of the island. Though there isn't any wifi in the house, there are plenty of free public hotspots all along the main street so we didn't have any trouble connecting to the internet during our stay.
