Effluent came up our bath!
I stayed here for a week during the last week of May with some friends. First off (as was mentioned in a few other Trip Advisor comments here) the lobby is just crazy! And not in a good way. We waited in line for about 20 - 30 minutes and then got told our room number and that was about it.....not very welcoming! 
On our first day we flushed the toilet and noticed water spilling out from under the toilet bowl. We rang the front desk and it took probably 4 hours to get this fixed, at which point effluent was bubbling up our bath!!!!!! 
Other issues is that our internet in our room didn't work. We called front desk, they said it wasn't their problem and to call another number which we weren't prepared to do on international roaming. They would not call them for us. 
In fairness to the hotel the location is great but do not go here if you're looking for a relaxing hotel. It's positively frustrating, loud and crazy getting into the lifts or through the lobby. On checking out we went to leave our bags in for a few hours before our flight. This whole process probably took an hour! 
On checking out we were not even asked for how our stay was or anything to that effect. We got no money off for having raw sewerage come up our bath. I made a complaint on the customer service page but no one ever contacted me back. I certainly won't be staying here again....
