Easy to reach, room size is ok, shower only with no bath tub. Most of the rooms has window but with no view because the adjacent building just a few feet apart. Room cleaning on required, otherwise new towels & bottles of water will placed outside door for replacement. No breakfast arrangement, only provide a free coffee machine 24 hrs available at lobby.
Decoration was a little bit old, dust could be easily find in somewhere.
Overall, Red Roof will not be my choice for next time travel in Osaka.
