My partner and I stayed here for 7 nights while traveling around the Kansai region. At first it was a bit difficult to find as Shin-Osaka is a massive subway/JR station bit once you find the correct exit, then it shouldn't take longer than 10 minutes to walk to the hotel. Be sure to use exit 4 when exiting/entering the Midosuji subway line and use exit 6 for the JR lines.
The hotel was clean albeit dated but considering that we spent very little time within the rooms and the building itself, it didn't really bother us. The main thing is that the bathrooms are tiny and the ceiling is low (total area is probably about 2 x 2 square meters, with less than 1 square meter of empty floor space) so it may be a bit uncomfortable to use for very tall/big people. The staff also only speak limited English so some knowledge of basic Japanese is recommended. Nevertheless, I would recommend this hotel for those looking for good value for money in a convenient location.More
