Unlike some hotels I've visited in Japan, the room was quite spacious with basic necessities. Bed was super comfortable, bathroom was clean and maintained. Also great customer service.
The only drawback for its room is the noise. I can clearly hear what's going on upstairs.
However, before my trip, there was a systematic error from its website. When I called . the girl from front desk told me, " Sorry but I don't speak English....."
I was then transfered to another guy who actually spoke poor English and told me, " Sorry, but I do not see your reservation, please call later."
I wrote to the hotel at kwg-frt@princehotels.co.jp (according to their official website, it's the only way to write to them.)
Sure enough10 days later, still no one replies me at all.
Will I return? Definitely not.
