I stayed at Grand Mercure in 2011 with my family and loved my stay. We were upgraded to the top floor rooms which were very luxurious and spacious. The hotel staff were all excellent, especially Akshaye the manager at the time. Breakfast was super too!
In terms of view and location, it is away from the modern part of Hyd/the malls etc but close to Charminaar. Many bargain shops etc near there. Hotel view is of a biryani restaurant and the busy Chirag Ali Lane.
