Stayed for one night, two rooms, including one with pool access. The hotel is located on the upper floors of an office building with the focal point being its centrally located outdoor swimming pool and various adjacent streams, ponds, waterfalls and fountains. Conveniently located across from Central Station, although there were not any restaurants close by other than the eateries located in the Central Station (and most closed early on a Saturday (5pm - 6pm)), the hotel is modern and the rooms comfortable, clean, and in good shape (with the odd paint peeling in the bathrooms). Depending on your neighbors, room soundproofing might be an issue.
The pool area can get very busy with few places to sit; the room with pool access does not actually have a view of the pool but rather the rock gardens that surround the pool. Nonetheless, their location is convenient for going to/fro the pool; other rooms make for a bit of a trek.
The restaurant is good, but pricey, as are the rooms generally. However, it is a typical Hilton with friendly and accommodating staff. We would (likely) stay here again.
