I am in agreement with other reviewers that this is NOT a 4-star hotel... not even by a LONG stretch. Someone at the hotel really need to learn what a 4-star hotel means.
This hotel is basically a slightly larger version of Japanese business hotel but without the clever use of space and furniture. I didn't have space to open my hardshell luggage and didn't have space on the desk space to have my laptop and a paper notebook at the same time. The bathroom vanity has zero space for any of your own items.
The hotel, however, is very clean and has all the typical Japanese-type amenities, including a bidet and large TV.
The breakfast is ran by the 1st floor lobby restaurant, a separate entity, which is a vegan restaurant. I can understand why it's a turn off for many - they didn't even have eggs or milk products. However, the vegan dishes are well prepared, tasty, but obviously very Asian, so for westerners, it can be an issue. I did enjoy the dishes because they use high-quality expensive ingredients as I enjoy soy, tofu, mushroom and vegetables. Perhaps it could be a good balance to those unhealthy street food people would eat in the nearby nightmarket.
