Emirates Plaza Hotel
A clean and simple hotel centrally located. Has the all the amenities you would expect from a budget hotel and centrally located. Please note, if you are after a peaceful quiet stay this may not be to your liking as there are numerous nightclubs in the building, all open during the week, so the noise may be an issue. You may want to enquire before you book.
