When I visited Osaka I stayed at the Hotel CLAITON Shin Osaka. It is close to Nishinakajima-Minamigata station, Midosuji-line, on the Osaka underground. It was quite a useful hotel, I will tell you what the hotel was like and how their service was.
The hotel is located right next to the Hankyu Railway but it was not noisy.
There is an Onsen installed at the top of the hotel, you can enjoy it.
(I didn’t use it though)
The room was like this :
It was a very small room but I think it is okay if you want to save money.
How to connect to Wi-Fi
You can select ‘claiton’ SSID.
Then type the password which is in the room.
Uploading : 1.87Mbps
Downloading : 3.43Mbps
It was so slow.
Especially at night time it was hard to stand.
I booked this hotel through Kaligo, which was not bad apart from the network problem.
You can choose the plan, with or without breakfast.
If you don’t mind the Wifi network being slow, it is worth considering staying there.
