We visited during the May Day holiday and upgraded to a lake-view king room by paying the difference in advance, which was a very smooth process. The hotel facilities are a bit outdated; the TV is an old non-smart LCD from years ago with no set-top box, so screen mirroring isn't possible, which was a minor letdown. The hotel also seems to be very understaffed; it took a long time for service requests to be fulfilled. Breakfast was a bit chaotic too, with a lot of people and even red plastic chairs in the restaurant, making it feel quite cheap. However, the view of Wanlv Lake from the window and the air quality were both excellent. The hotel only has three 20kw fast chargers, and all the slow chargers were out of service. Luckily, there were hardly any gas cars occupying the spots, and most people moved their cars promptly after charging.
