Cave house is awesome. Location is perfect for sunset views and convenient to all of the shops and bus station. Make sure that you are in shape because the walk down and back up the steps every day is quite steep. The crowds do tend to congregate around the cave house to watch the sunset but it is quiet the rest of the time. Breakfast is delivered every morning at 9 AM and the view over the Caldera makes for a great way to start the day. Also check out Petra Kuzina for a great cooking class and Santorini day tours for a catamaran cruise
