This AirBnB is nice, but the photos oversell the flat. Two important things to note: First, the flat is very dark abd the "balcony" is not really a balcony. Plastic fencing covers the entire area and your neighbors can look directly into your unit, limiting privacy, sunlight, ans a view.
You are literally staring at a plastic fence, even on the fifth floor. Second, as mentioned in the ad, there is no air conditioning in the unit. We stayed in the winter and it was still warm - I can't imagine what it would be like in the summer. I would also note that the gym is very basic - two treadmills, two ellipticals, and 5 weights.
The location is great and the rooftop is very comfortable.
