Book as fast as you can! Location: Best of both options. It is located right in the middle of the main pedestrian walkway, one of the closest to the village entrance- yet-seriously!- the solid door, high white walls of the private courtyard block the crowded busyness out very effectively! You walk into your own serene oasis of shaded calm before entering the building itself.
Place: very clean and absolutely charming! The cozy kitchen and entry is perfect for two. The swirling stairs to the spacious bathroom upstairs add a beautiful touch. The bathroom is expansive and dreamily tiled, good shower pressure and hot water! You can even look out over the crowds from the discreet tiny window and see the sunset colors if you shower in the evening! The bedroom is high vaulted, tastefully decorated, very big and air conditioning works wonderfully. It's also well insulated from the lively late night bar noise that's a block away- perfectly quiet. Again, best of both options for nightlife or peaceful sleep!
View: perfect view of sunrise and caldera from balcony. Almost 360 private view of Oia from the shared roof terrace (lounge chairs, benches and table, umbrella shade) with only one beautiful restaurant rooftop seating obstructing the actual sun orb of sunset. However, with a little creativeness even that can be overcome. Unlike most houses in Oia where tourists are walking around your place and hanging out just above your porch- this is the top row of buildings perched along the cliff, so remarkably: hosts are incredibly gracious and private (and you look down everyone else' balconies and terraces).
Service: very sweet hosts, readily available, their restaurant is one of the best for location, price, view, friendliness and solidly tasteful food. We ate there several times. Already planning to come back to this place in Oia as I write this...
