Travelled with my sister and stayed for 8 nights - great location with lots of restos nearby, short walk to Yodoyabashi Station, which is on the Midosuji metro line that takes you to all the important places, and, most importantly, a Family Mart right next door.
Room cleaning is mandatory every 3 days, which worked great for us. The room itself was a great size (lots of space to open 2 large hardside suitcases), except for the entryway, which was really cramped. Beds were super comfy and the firm pillow was amazing. Temperature control also simple to use.
The laundry room is a bonus (there's an option on the tv to see which machines are in use and for how long), but be prepared to wait, as there are only 3 machines (also important to note that the machines only take 100 coins, so go to reception if you need to exchange other coins); the dryer function is terrible if you're washing a lot of stuff, as you will probably need to pay for extra drying time.
