"The Centara is a beautiful, modern hotel, with everything you could want. Most importantly, it is only a short walk from the Midosuji subway station. This is so important. There is direct access to the subway from the hotel via a skywalk through an outdoor mall. From there, you can take the line straight to Shin Osaka station, and get almost anywhere in Japan from there.
If you are serious about traveling around in Japan, you want a quiet, soundproofed hotel with this level of access, and this is it.
The staff were friendly and the room was amazing. I had a beautiful view of the city below, as well as a full-size king bed and a wonderful shower and bath. I almost did not want to return to Tokyo (and I regret that I did.)"
