We found it very difficult to carry our luggage and personal effects from the car park area to our apartment. If we used the lift it was 50 meters from the car and another 50 meters from the lift to our apartment. If we used the stairs to the apartment from the car park or visa versa we had to climb or descend 50 plus stairs. Phew !!!! This, of course, is a design fault.
In the apartment, the fridge wouldn't run without freezing everything (even after adjusting the temperature controller). The shower head was faulty and also was not compatible with the low water pressure. The carpet was obviously very old and stained ( probably beyond cleaning). The furniture was old, damaged and poor quality. There were no tea towels in the kitchen. None of these issues meet your description of " luxury accommodation ".
We will say that the bathroom, with the exception of the previously mentioned shower, was fine, and the bed and sheets etc. were good. The view was exceptional but was ruined by the afternoon and evening noise of all the small school kids screaming, shouting and doing "bombies" right below our balcony. (not your fault of course but very annoying !!!! We hope many of these situations can be rectified to benefit your future clients.
