We had the deluxe room which sleeps 6 people, it is pretty much the biggest room we have in japan and the best considering we stayed in Hilton, mystays, ryokans, etc. price is reasonable, room is clean and big, bed is nice and toilet/shower is separated which is a nice feature (all other hotel has them in the same room and really tight/small).
Location wise it is not too bad, around 5 minutes walk to jr namba and 10mins to dotonburi. It is in a quiet area though and not where all the action is - if you like it that way then this is for you.
A family mart (24h convenient shop) is just around the corner. No laundromat spoilt it if you do want to wash cloths, need to go to dotonbori or other places which take 10mins.
