Wonderful place with amazing views. It was always a pleasure to open the window in the morning or stay seated outside. The hosts provided everything needed plus extra towel for the beach, bottled water, jam and some extra for the breakfast.
Ammoudi is nice, with good (fish) restaurants, but we had problems get there and out. The access is via a road that is too thin for traffic in both directions. During high season at least, often the traffic was blocked. Also, as it is close to Oia, the taxi drivers are not willing to "waste" their time going there, so expect to wait quite long till you are able to get there/out. The alternative, of course, is to go up/down using the stairs (or ride a Donkey for €6/person). This is not horrible, but be aware of that. Maybe for long stays, than it becomes tiresome.
