There is no AC in this unit, just a fan on the wall. When sitting directly in front of the fan, it wasn’t so bad.. but it was hot. I’ll take the blame for not noticing before I booked. The unit also didn’t appear to be cleaned very well before we arrived- the sink had gunk in it and there was a used ketchup packet on the floor. While sleeping, I was bitten by a centipede that crawled up into the sheets in the middle of the night. We were not able to fall asleep after that.. This is a ground floor unit with a door that isn’t framed very well, so I would guess this is a normal thing.
