The check-in instructions were easy to understand and the place was well located and clean. We had everything we needed and it was a very enjoyable stay.
The train station was a short walk as was the Korea Town high street with lots of atmosphere, shops and food options.
It isn’t directly in Shinjuku, you do need to walk a little while or catch the train to get there but this didn’t cause us any issues.
I would recommend this place.
