NO AIR CON!!!!! My wife and I went to Sydney on its hottest weekend on record, and we booked Carolina's place for its claim of having air conditioning. A fan by any right is NOT an air conditioner.
Carolina was kind enough to organise another fan for us, but with 31° in the room overnight it made little to no difference.
The unit itself is pretty cool, with decor to suit the modern hipster. The pics on the ad show pretty much exactly what you get - a very thin and cramped area with a steep staircase. The bedroom upstairs is fine, but there is no safety feature where the stairs begin to stop you from falling down them.
Overall, if the temps weren't so hot, we probably would've enjoyed our stay slightly more. The layout of the unit is as it is, with prices to suit, considering its location.
