We really enjoyed our stay at Warwick, it's centrally located, so close to downtown, Corniche, Zaytouna Bay, and a short walk away from Hamra. The staff are super friendly, the room is comfortable and clean, the pool is really nice and the gym is OK. It also has a breath taking view from the roof and restaurant, and the food was very tasty.
The only thing we didn't enjoy is that it gets really noisy at night due to proximity to a club across the street, it gets really loud and on 3 out of the 4 nights we stayed, we weren't able to sleep till 3 am when the music stopped. I would encourage the hotel administration to improve window sound proofing - that would have made the experience perfect.
