Recently stayed here in early/mid-June and appreciate Antonis' and Stamatis' response times from the time of booking until I checked out. Their place has an amazing location by the castle (where you can catch the famous sunsets). We weren't able to get a full view of the sunset from the patio during our stay but if you walk 1-2 minutes away, you can catch some fantastic views. I highly recommend staying here if the main purpose of your visit to Santorini is to see the sunset and walk around Oia.
