Beautiful rooms, excellent facilities, spacious and comfortable. Clean and frequently cleaned, staff are professional and multilingual. Multiple gardens and leisure facilities in hotel.

Shinagawa is something of a dead area. Also, the hotel is uphill from the train stations, walking up with luggage is a bit of a pain.

Staff were exceptional and helped to make our stay perfect. The location is pretty good and well-connected, and the rooms are clean, spacious and comfortable. The garden is a nice touch and everything about the hotel, from common areas to amenities, communicates high quality and luxury.

Only central heating is available until the summer, so if your room is already hot (as our original one was before we were offered to change it), it is very difficult to cool it down. Furnishings are slightly dated, but in a good shape still.

Excellent location, close to a big train station with many lines specially the Shinkansen line, makes travelling very easy. Having a 7-Eleven shop inside the building is super handy. A big and beautiful Japanese style garden is a plus, specially at night when the lights are on. Good view of the city, you could see the Tokyo Tower. Stuff are nice and helpful, room is clean and well supplied.

The interior of the hotel room is a little out dated, specially the carpet feels very old.

The room size were very spacious for Japnan. The rooms were also very quiet and they back on to a quiet area. The garden in the hotel grounds is beautiful. Having a convenience store not far from the lobby was fittingly convenient.

The staff were efficient but came off a bit cool/indifferent. The hotel is up a hill from Shinagawa station up a slope - only a big deal if you're carrying lots of bags - a shuttle service from the station would be ideal.

Spacious clean and well functioning room, beautiful garden and balcony view of the garden and city. Very close to station for easy transportation.

Difficult to find with 3 other Grand Prince hotels in close proximity. Hotel is up a steep hill so if your walking from the station with suitcases be prepared. Buffet breakfast was very expensive so we opted to have the American style breakfast which ended up being approx. $15 cheaper and didn’t exceed our expectations at all. Disappointed the pool was closed as it was 35 degrees in Tokyo.

The room is big, great for couples. Though the location is quite far from the station, not so convenient when you have big luggages, but there's shuttle bus if you are not in a hurry to drop you off at the branch near the train station.

The way to the hotel that we have to climb up after a long walk in Tokyo.

Amazing views of the city from the balcony, with beautiful sunset and we even saw Mt Fuji one day in the distance. Nice gardens at the bottom which makes it feel even more spacious as you do not have any high building in front blocking the view. Very big room, especially for Tokyo! Great location: only a 5-10min walk to Shinagawa Station which has many trains into the city and a direct train to Haneda Airport (only ~20min). This area is much less crowded than Shinjuku or Shibuya, which we really appreciated after spending the day exploring the city. 7-eleven in the hotel building, which was practical to get out cash, buy some snacks etc. Staff was very helpful and spoke good English (as it should for such a hotel), they helped us get a package delivered to the hotel, informed us when arrived, brought it up to our room.

I would not rate it 5 stars, rather 4. The rooms are not modern enough (especially bathroom), but we knew that from the pictures when booking so no disappointment there. Check-in machines: they have them a lot in Japan but I would have expected to have someone do the check-in for me in a 5 star hotel by simply giving my passport, rather than having to use their machine to find my reservation, pay for city taxes etc. Beds could have been a bit harder (personal preference), softest beds we had after 2 weeks in Japan.

location is very good, it near Shinagawa station which can directly reach from Narita Airport with NEX Narita express and Taganawagai station which allowed us to navigate local metro network. There is a 7/11 shop inside hotel, you can find drinks, food, snacks, mask, umbrella there.

There is no shuttle bus from Shinagawa station to hotel, we need to carry luggages and up hill about 400m to hotel

Sakura garden is phenomenal. Close to Shinagawa station. Neat and clean location. Balcony plus view. Size of the room is massive as per Tokyo standards.

Old property. Worn out equipment.

Very good location. Easy to travel around Tokyo. Very friendly and helpful staff. Great garden. Has small 7/11 shop on premises-it was very helpful.

Very steep hill to come to hotel from station.
