all villa including studio have a balcony at OKW.
that say, try for a 2nd or 3rd floor.
the first floor studio balcony can have little to see - sometimes they surrounded by bushes. Othertimes they are next to the air conditioning units.
lots of time they are handicapped so no shower.
so go for the 2nd or 3rd floor studios. there is no elevators except in 62, 63, 64 building.
