We will be in Santorini for about 4 days the beginning of April. We have two little boys (1 and 4) and would like to be in a good location for relaxing and enjoying the outside. Close to restaurants and little shops would be nice. If it's a hotel, we'd love to have a pool (and maybe one that is heated since it's not the middle of summer). If an apartment, a good location close to the beach... my kids love the sand even if the water is cold. I would like to stay under $200/night. A good view and atmosphere is preferred! From what I've already read, it looks like the main areas are either Fira or Oia.
