The only issue to note is the restricted air flow in the backside / street side unit. It gets uncomfortably warm. There is a box fan, but it is wobbly (as they are) and requires a counter weight to keep from rattling.
I left the box fan on, while I was out, to keep the unit from being hot upon my return. It was noisy enough that the owner needed to access the unit in my absence to turn off the fan due to the noise it was making.
There are two units, one is indeed facing the beach with a window view of the ocean while the other unit is on the backside corner / street side. Due to the unit being on the backside corner of the large home the air does not cross through the unit.
Just an FYI. Everything else was fine.
