2nd time to stay in the hotel;1st time I stayed on 8F and this time on 4F.
Room of improvement in Wi-Fi infrastructure. Internet connection was quite unstable and I was disconnected from internet around 7-8 times during my stay of 2 nights.
In particular, I used my PC to reserve High Speed Railway (HSR) tickets in my room (4F) after breakfast via hotel's Wi-Fi but internet access was unavailable.
Eventually, I used tethering and shared my mobile network to my PC for HSR tickets reservation.
