In a lot of ways, I prefer a room on the 1st floor at OKW. No stairs to climb after a long day of walking in the parks.
I've stayed in 1st floor OKW rooms twice and never had a noise problem from people above me. Still had excellent views outside my balcony on both occasions.
I guess there could be some dense foliage that might grow up around your balcony that could make having any kind of view very difficult. But the stairs thing was worth it to me.
