I rented the deluxe suite, but I was upgraded to the superior suite. It is on the top floor with a stunning, panoramic city view with a huge balcony.
The hotel is very new and the service is very friendly and helpful. The breakfast is a nice perk, but it could use more variety.
My room was very nice, but the AC stopped working after several days. I assume they will fix this eventually.
The wireless internet was fast reliable, and the signal was reasonably strong for my laptop (but not my smartphone).
The location is fantastic if you are attending conferences at the nearby conference center. Its also a great hotel for extended stays, owing to the kitchen with microwave and refrigerator. This is a rare luxury in Europe.
Also, the location is fairly quiet (no road noise), except during Ramadan. Also, the noise from other rooms is audible, but not too bad.
Overall, I was very happy. The only complain I have is that the maid service was a bit inexperienced and the rooms could be a little bit quieter. They forgot to replace the laundry bag, etc. But a call down to the front desk quickly cleared this up.
Honestly, the quality and comfort of the room, combined with the good service and incredible balcony view really made this hotel an awesome experience. Go for the terrace / superior suite--its worth it.
