I stayed at Best Western Osaka Tsukamoto, when I visited Tokyo as a business trip.
The hotel is located close to Tsurumi station at JR Keihin Tohoku line or Keikyu line.
As I am a Diamond select member of the Best Western hotels, I got upgraded to the room below :
There are nothing universal sockets.
How to connect to Wi-Fi
You can select “BW-YOKOHAMA” SSID.
The password will be provided at the reception.
Uploading : 8.31Mbps
Downloading : 9.01Mbps
It was good, I was able to talk with video FaceTime.
I credited the stay reward to Avios, however it has not been credited yet even after claiming.
I am wondering if it will be surely credited?
