Ascott is one of the best amongst all serviced apartments. Top notch configuration in the rooms and facilities at the property. I stayed here twice over two week's span. One time, I even got upgraded to a one-bedroom suite. In addition to a wash/dryer combo, the suite had a full kitchen with a very large fridge. Bathrooms are modern with tubs and showers. In the suite the toilet gets its own little glass cubicle. Bathrobes are provided. I always appreciated the quality furniture in their rooms/suites. No exception here.
At this location in Foshan, the lobby is on the 25th floor. Check in and out was a breeze. There is a coffee machine free for guests and visitors to use. Breakfast is decent with a reasonable variety of food and drinks. Both western and local Cantonese styles. The gym is on the lobby floor too. Facilities are decent but the towels and water dispenser are well hidden in a corner tucked away. I had to ask where everything was.
One complaint was that in my first studio room a few lights malfunctioned the 2nd day. The resident electrician fixed them rather quickly. But that was kind of out of character for Ascott. Not a big deal though. Also, keep in mind, if you have any guests visiting you in your room, the registration process for the guests can be rather tedious and time consuming.
All in all, I'd still recommend M-City over many brand name hotels in Foshan.
