We booked a family sized room for two people, and find the size comparable to North American hotel (probably much larger than a typical hotel in Japan). The hotel is clean. Staffs are friendly and helpful. It's really close to Dontonbori but a slightly longer walk to Namba station, but it's definitely doable. Thankfully, this station is really convenient for travelling short & long distance. I would definitely consider booking with MIMARU again, if we were to come back to Japan.
