We had an overnight stay at the Movenpick Deira.
We arrived early at the hotel (08:00am), although the booking said the earliest check in was at 14:00, the receptionist went out of her way to accommodate us as best as she could. No rooms were immediately available, but she gave us access to the pool & gym facilities, until a room was ready for us a few hours later.
Our room was large, very clean, modern with a King size bed that was the most comfortable sleep I've had in ages. The hotel is located in the down-town part of Dubai, with easy access to the shopping malls, and most attractions.
We had the breakfast buffet, which offered a wide range of hot and cold food, and was pretty good.
We used the bar at the hotel, but found it to be a bit soulless and dark.
The pool is on the roof of the hotel, which is excellent if you are a plane spotter, as its almost under the Dubai flight path. The pool area is quite small with limited sun loungers, but we enjoyed it for the couple of hours we were there.
Overall, for the reasonable price of the room, cleanliness, comfort and central location, I would highly recommend this hotel. If you are looking for a hotel for primarily leisure facilities, better look at the Jumeirah beach hotels.
