It's a very large hotel, but the rooms have definitely seen better days. The air conditioning in the rooms is quite poor and we found several loose electrical wires poking out of the walls (hopefully not connected, but we avoided just in case)
Our initial room had balcony doors that couldn't be closed, leading to an early wake up thanks to the building site next door. The reception staff were helpful, offering alternatives, some with similar door problems, but we did eventually end up with a room that, while not exactly quiet, was at least better than the first.
Noise aside, the rooms were large and comfortable, breakfast was good and very varied and the hotel is in a pretty decent location.
We tried the hotel restaurant one night, too and were very happy with the food.
