The spa at Sultan Plaza Hotel has a mixed reputation among guests. On the positive side, some have praised the spa area as nice with improvements made to the spa jacuzzi, which now maintains a pleasant, moderate temperature. However, there are notable drawbacks mentioned in the reviews. A recurring issue is that various facilities, such as the sauna and hammam, were frequently out of order or required a wait for heating. Additionally, the overall level of cleanliness and maintenance has room for improvement with instances of a dirty pool and rusty lighting fixtures in the hammam being highlighted. While the spa has potential, consistency in its upkeep appears to be lacking.
