This hotel has the worst soundproofing I have possibly ever witnessed. The traffic noise was solved by changing a room facing the back of the hotel, but the sound from the hallways and other rooms is unbearable. Get ready to be waken up at 7am and listening to people banging doors in the hallways until past midnight. I had earplugs and a white noise machine and still barely could sleep. This is not a five star hotel by any means.
Lots of positives too: The sunbathing are by the pool is actually quite nice, the breakfast was incredible, housekeeping staff were super nice and attentive, and the location adjacent to one of the best shopping malls in Dubai is great. The metro is also easy to use (just buy a NOL card from the station, top it up an swipe it when you enter and exit the metro, it'll be 3-5 dirhams per trip) and next to the hotel. Don't take a taxi to the airport, the metro will cost almost nothing and it's faster and very convenient.
Overall, I'd recommend this as a one-night stay to do last-minute shopping if you can sleep through all the noise. Don't expect a five-star experience, though.
