We are a family of four with 12 and 14 years old kids. We plan to visit Santorini and Athens. Any advise on where to stay in Athens and Santorini would be greatly appreciated. We plan to spend 3 nights in Athens and 2 in Santorini. We are looking for a 4* accommodation. Also, where would you think is better to spend Good Friday - I am afraid if tourists places might be closed!
