Only if there are no cruise ships in the harbor.
Santorini is a busy island but gets massively busier when cruise ships do arrive.
If no cruise ships it is not busy in Oia. Anywhere is a spot where you can watch the beautiful sunset. Make sure you have as well a good view away from the sea to the little white houses and chapels in Oia as the light is brilliant during the sunset... And the view on the little castle is stunning!!!
When cruise ships are there it gets tough. Crowded!!! No way to go there if not be there 3 hrs before the sunset!
If you are a part of such a cruise ship... Don't complain about the bad view or the crowds or whatsoever ... You are part of it :) ... But reserve in advance in a restaurant with top view ... More relaxing
