All request was answered immediately. They also help arrange all kind of transfer and tour, which helps us a lot. All rooms has double-glass window so it is quiet even it is near the center.
However, I think the duplex is better for max. 8 people. Because it was very small for us 10 people. The electricity will be out easily that you cannot use the stove and hairdryer or other high watt equipment at the same time. Although there are 3 bathrooms but it cannot be used either two of them simultaneously because the water will be too small and cold. In sum, it is a nice duplex and would be more comfortable for less people or if you don’t use much of the house equipment.
