Hi The apartment we stayed in was immaculate, basic but cleaned thoroughly daily inside and out.
We heard no noise at all, the nearest lively bar is The Planet Bar which is a 2 mins walk, Maybe if you were in the apartments backing out that way you may hear something, cannot comment.
The airport is a nightmare, we were there about 4 hours, there is nowhere to sit in departure lounge if it's busy. It's very expensive too. My advise, wear old clothes you don't mind getting grubby as the only place to sit is the floor! Secondly take plenty of food and drinks in your hand luggage in case of delays because of the prices. Not sure about weather, went in June
