Ok, let's say an apartment is U shape.

  -------------- Block A
  |
  | Block B                                  Sea
  |
  -------------- Block C

Ok, let's say

Block A
a) facing outside - will look at seaview with morning sun with low cost flat view at left
b) facing poolview - will look at Block C with seaview at the left (afternoon sun)
Block B facing pool + direct sea view (side view of Block A and B)
Block C
a) facing outside - afternoon sun with low cost flat view at right, seaview left, and direct is some terrace house
b) facing poolview - will look at Block A with seaview at the right (morning sun)

Which one is the best?
