Yes, but not the Seiyo Ginza. I havent stayed at the Park Hyatt, although a frequent visitor I know who stayed there is the one who told me of the Seiyo Ginza, after he switched to the latter. I did stay in the club level of the Grand Hyatt in Tokyo and at the Seiyo Ginza for 2 days each during the same trip early last year (a few days in Kyoto in between). The Grand Hyatt regency club level was extremely nice but not even in the same category as the Seiyo Ginza in my opinion.

When we arrived at the Seiyo Ginza the doorman on the ground floor took all our bags and showed us to the escalator to go up one floor to the lobby. When we arrived, he had called up apparently and they were waiting at a small desk with chairs with all our check in materials ready for us to sign. They dont really have a check in counter. After the brief check in, the assistant manager showed us to our room. It wasnt a suite, although it might have been the slightly higher priced room, not the lowest price. When we entered there was the sleeping area, and a small sitting area with a 2 seat sofa, some plush chairs and a desk. Off to the left at the far end of the room was a large dressing area with a vanity. Right as you came in the door to the room was a walk-in closet. Yeppers, a walk in closet in a hotel in Tokyo. The closet was about the size of some rooms Ive stayed in in Tokyo. Exiting off the vanity was the large, very nice marble bathroom.

As the assistant manager was showing us the phone he suggested that rather than trying to remember which line to call for which service we just call the butler line and our butler would take care of it for us. After we were shown the room we were asked if we wanted tea or anything else. We asked for tea and a high speed internet connection. He left and a short time later a woman in a butlers uniform appeared with a silver platter bearing a tea service and an internet connection which she hooked up in the room.

The concierge was fantastic. They gave us some great tips on restaurants that arent frequented by tourists but rather Japanese businessmen in the area. Room service breakfast was also a real treat. Service throughout was outstanding. All in all I cant say enough about them. Ive stayed at Ritz Carltons, the Connaught in London, L'Hotel in Paris, numerous Hyatts and ICs and the Tawaraya Ryokin in Kyoto. Only the Tawaraya topped the Seiyo Ginza in service the rest, while very good, werent really close. But the Seiyo had nicer rooms (MUCH larger) than Tawaraya. Enjoy it.
