This is the worst experience ever. The hotel is based in "not so great" neighborhood, on a main very noisy road. Half of the rooms are facing the noisy street. If you close the balcony doors and use earplugs it could be bearable. You have to close the bathroom as you hear any use of toilet of your neighbors. But the real challenge is that you can't control the air condition from the room and this forces you to open the balcony door - then you're doomed. Syngrou staff control the air condition for you, and the lie about it. The first reception lady asked which temperature we wanted, and said "no problem, I'll set it". Then at 1am we woke up sweating, no air in the room at balcony door had to be closed. We went to the receptionist (different person, night shift) that said they can not really control it and there's nothing he could do about it (again, lie). We asked to change rooms, we asked to turn the air-condition, we asked to talk to a manager, but nothing... Then we escalated to hotels.com at 1am and had a sleepless night trying to find another hotel. We finally did. In the process, Syngrou did open the air condition for a few minutes and then turned it off again. After a sleepless night, we moved to a different hotel. The hotel seem to have great marketing as grades are great. If you look closely, you can find several google reviews with similar experience about staff that would lie to you, noise, air con... don't fall for a good grade. Check it, I would say avoid it.
