It was my first time in Japan, and I was super nervous about trying to check into a hotel on my own when I didn't speak their language. Definitely check your hotels to make sure they speak a language you know, by the way!!
Palace Japan Hotel was wonderful, and most of the people at the desk do speak English! Even if they do not, they still try to help you to the best of your ability. They are so friendly and helpful! Even when I couldn't communicate with one of the ladies at the desk one morning, I just brought out Google Translate to try and communicate and she understood enough to help.
If you're looking for a nice place to sleep, no matter how many days, and aren't concerned about the size of the room, this hotel is perfect. The room I was in was relatively small, but I had no problem with it.
There is an elevator, which makes bringing your suitcase up and down the place so much easier!
The other nice thing is there is a 7-11 and other markets nearby, plus a café. Super convenient! The neighborhood is actually relatively quiet, which is wonderful, and I could walk late at night and still feel safe.
The train station is about 10~13 minutes tops when walking from the hotel. The way between the station and the hotel has elevators as an option instead of the stairs, which has been a lifesaver for me since I had two suitcases.
PLEASE bear in mind the SOUTH station has escalators that go up, but none going down, so you have to carry your suitcase up/down, depending.
