I would actually rate this hotel a 4.5, if possible. The Strings is a lovely hotel, with exceptional servlce. I felt very posh staying here, as you take a elevator to the 26th floor to check in. With the exception of 1 person, I encountered, over the phone during a 6 night stay, everyone was professional, gracious and always followed through with a request. The room was very nice, and I slept very well. Great Tokyo location. I would stay here again in a minute. The Fitness Center has a wonderful view of Metro Tokyo.

The only faults are when selecting a room, ask reservations for a room on the other side of the train station. You will hear the trains all night. Also, the pillows were a tad uncomfortable. Finally, the two onsite restaurants look very nice but they are expensive. No worries, any possible type of food is within a 5 minute walk of the hotel.Check out the Queen's Setan Market adjacent to the hotel. I amused myself in there for hours, as a curious American.

Stayed at the Strings Hotel and booked the Club - Deluxe King package. 2 nights stay with breakfast at the Dining on the lobby floor. Quoted price does not included taxes, service charges, etc.
Pros:
Elegant design. Turndown service included a takeaway Bear.
Bathroom was very ergonomic.
Free mini bar in package.
Convienient to the Shinagawa station.
Cons:
Was cheaper for me to stay at Mandarin Oriental on a corporate rate, a much better hotel.
Included buffet breakfast was not impressive. Slight changes between days. Not much of a selection.
Service was good, but not exceptional.

I'm surprised Strings Hotel isn't further up the Tokyo hotels list. I wanted to book Park Hotel, having stayed there before, but Strings was agood second choice and in the end slightly more enjoyable/more convenient.

I stayed here with my s/o for two nights over the weekend. We were in Tokyo specifically to go shopping and found the Strings' position - right near Shinagawa station - to be ideal. Being right on the JR Yamanote line, we could access Harajuku, Ginza, Shinjuku and Akihabara all within 25 minutes. Shinagawa is also on the Narita Express line from the airport, although we preferred the hotel's shuttle bus and airport limousine bus.

The rooms were compact but not at all cramped - and seemed spacious and light. The bed was like sleeping in a cloud, the water was hot, there was a cute love seat, a scattering of expensive coffee table books to read, the furnishings calm and zen-like, not sparse or tacky, a cd player with a cd of ambient music - it was all very well thought-out and welcoming. Service was great and we booked through Tablet, so got free breakfast and afternoon tea/lunch every day. Getting food of that standard - 5* restaurant - for free was amazing to us, since the meals were worth about 7000yen.

Other hotel patrons included rich japanese people there for shopping, families on holiday, wedding attendees (there were 2 weddings while we were there) and hip young couples (like us, of course).

Overall, it was like the perfect place to stay. Serene and stylish, with easy access to all of Toyko. Cheaper than the big name hotels as well.

beautiful lobby, perfect service during checkin,
very helpful staff. nice, big, nicely furnished room with excellent view. one of the best business hotels I´ve ever stayed at, good value at approx. US$ 200 including buffet breakfast.
