I stayed in the Daiwa Roynet Ekimae for business for 3 nights. Overall, I was really happy with the choice. The hotel is relatively new and rooms are in good condition. The A/C works great (once you figure out which mode is Air Conditioning!) It isn't self explanatory and only is in Japanese, so I had to ask the front desk clerk who happily explained which mode was A/C and not just fan.
The bed was comfortable, they have actual Wireless internet (a rare treat in Japan), the breakfast is basic, but good with a choice of western or japanese in adjacent coffee shops and the room was clean (expected in Japan). Overall, it was a great choice and I would stay here again!
