It was our first trip to Japan and we spent our first 2 nights at Grand Price Hotel Takanawa. Overall, we enjoyed our stay and below are some of the pluses and minuses we experienced.
Location is good and easy to find. It's close to Shinagawa Station--about 5 minutes walk but you have to walk up the hill to the hotel (other Prince brand hotels are a little closer and with no uphill walk). I think location makes it a good place for those who are not familiar with Tokyo. Narita Express (certain cars) stops at Shinagawa Station so we were able to travel here directly from the airport without changing trains (saving us from dragging luggages to board crowded commuter trains). Although there are not a lot of attractions nearby, JR Yamanote line stops at Shinagawa Station which makes traveling to Tokyo's major attractions easy. Shinkansen (bullet train) to Osaka, Kyoto, and Nagoya stops at Shinagawa Station, so traveling to and from these cities is easy also.
The hotel has a nice garden which is shared with another Prince hotel. When we were there around the end of March, Sakura (cherry blossom) was in full bloom which made the garden very beautiful and a nice place to stroll around and relax.
We heard a lot about how small hotel rooms in Japan were but it was a pleasant surprise to see our room was fairly spacious. (It was bigger than other hotel rooms we stayed in during our trip while paying about the same rate). It had a nice garden view. (Rooms on the other side had view of Tokyo Tower). Wire internet was also available from the room and they had wire ready to use in the room.
The hotel's AC system can only be set to either cooling or heating at a time for the whole hotel. When we were there, though the weather outside was cold, the room was a bit too warm so we wanted cooling AC system. However, only heat could be used at that time. So if you go there during certain seasons (spring or fall), you might not get what you want as far as AC is concerned.
The hotel has a number of restaurants but I couldn't comment on food quality as we didn't dine in any of them. They are much more expensive than restaurants around the station.
We also noticed the sign saying that the hotel provided shuttle service to the airport. The price was comparable to Narita Express, so it can be a good alternative if you don't have JR Pass. Again, we didn't use it, so I can't comment on it other than the fact that it's available.
Staff were nice and friendly. Check-in and check-out process was quick and easy.
Overall, I found Grand Price Hotel Takanawa a good hotel to stay in Tokyo especially for the ease of commute (within Tokyo, to/from the airport, and to/from other cities). It's particularly beautiful and can be a destination by itself in spring when Sakura is blooming!
