This unique hotel is situated right next to Imperial Palace - go on and take a peak at the royal grounds from your hotel window. Place was opened in 1890 to cater to 'Westerners' needs, but was not succesfull at all. Second generation was designed by famous architect Frank LLoyd Wright, and even partially survived Great Tokyo Earthquake on the very day of its opening! Then, hotel has been demolished and built from the scratch again in 1967.
Today it is still one of the most central locations in Tokyo, so your stay will be very convenient. Of course you can expect every convenience you can think of from the hotel with "Imperial" in its name: yukatas in the room, multiple restaurants, spa, fitness centre, tea-ceremony room and...music room, where you can practice your piano skills(!) Great location and service!
