I went by motorbike and the security at the lobby only drove down to basement B1 but did not flow guests to show the elevator to the reception to check in, the basement was dark and narrow and there were many dangerous signs prohibiting approaching, I was scared so I did not dare to go near to find the elevator entrance and the hotel also did not have any instructions or a map of the way, I had to walk along the tunnel path which was very steep and tiring. The soundproofing in the room was poor, I could clearly hear every step outside and vice versa. Everything else was ok.
