I stayed at grand president last summer in one of the suites in tower 2 and i didnt notice any changes from earlier visits. They are still Guest friendly so if they changed management the policies are still the same.
there are a lot of birds at the ambassador hotel Aviary right next door and that has irritated me on past visits, but last year i noticed that they have sealed the windows so the noise don't penetrate as much anymore.
Only thing that has irritated me on the last visits is that they have had no room available for med when i arrive very early in the morning, but i guess that is my own fault for not booking a room from the previous night.
