Stayed at the Yokohama Sheraton twice in a week and a half on my recent business trip to Japan. First day the vendor I was visiting booked a single room for us. For my taste and comfort, it was a little small, although not much smaller than any other hotel room you will find these days. Nonetheless, I inquired and was able to upgrade to the Club floor.
The Club floor is located on the 26th & 27th floor of the hotel, and the views from each room was spectacular. The rooms themselves were very large and very well appointed, the bathrooms, were outstanding and had these beautiful glass showers that are very elegant. All the amenities were excellent and the rooms were immaculately clean, as is everything in Japan.
The one issue I had with the Club floor was the size of the Lounge and the services or lack of services in the lounge. They did not seem to provide a lot of food or snacks that you would normally find in most lounges. One night I went over to enjoy the evening food service and found one bowl of some type of salad or something, and it was completely empty. The bowl looked like it had enough for a serving of maybe 6-8 people. Unfortunately, there were only about 4 people in the room, so I obviously missed out. It appears that Sheraton in this particular location is more interested in the rooms than providing any extra Club services, which is fine, I really didn't mind that much, but I did notice the difference.
The hotel is directly across from the Yokohama Train Station, and in the middle of an area very generous with restaurants, clubs and shopping. Big departments stores, luxury stores, great food outlets, and, the station itself is a truly happening place, it seemed busy all day and night.
All in all, really nice hotel, good breakfast, good service and excellent views from the Club floors.
