The listing is clearly not changed based on the season. There was a window washing platform parked on the balcony, caution tape on the rooftop patio, pool and hot tub are not operational, no grill as stated, and the entire road in front of the building-parking was blocked. After driving around the block 3 times, we simply drove past the "road closed" signs.
For the apartment, several lights did not work and the kitchen was not clean. The knives are not at all sharp and the only pair of scissors in the drawer were broken. There was no frying pan so we had to go buy one (brought steak for the grill).
The walk to the beach was just outside the building and it is on the boardwalk, so a plus there.
I would say this is not a great "off season" place to stay unless it is better explained as to what you will not have. I have hopes that the regular season accommodations are better suited to the listing.
