I must have stayed at the Granvia on about 15 occasions over the last 10 years, and it's always reliable and always good. This is the first time I've posted a review for it.
The rooms are good sized (especially for a Japanese hotel!) and very comfortable. The haven't changed in 10 years, but they still look well maintained and not at all tired looking.
The hotel has some excellent (albeit expensive) restaurants, but, being located over Kyoto Railway Station, there are literally hundreds of dining options within 100 metres in Porta underground shopping centre and in The Cube on the 9th/10th floors of the station building. Some of them are very reasonably priced.
The staff are excellent and extremely polite and courteous...most with an excellent grasp of English.
The only thing that could be significantly improved are the "health" facitities, which are quite disappointing. The gym is nowhere near the standard that a hotel like this should have.
Overall though, this hotel remains one of Kyoto's top hotels.
