I stayed in a single private room and I would reccommend this ryokan to everyone reading. Homeikan is beautiful, clean, and airy. They offer traditional Japanese breakfast to your room and can make it vegetarian. You can also use the private bath. Not very central but easy to find from todaimae station (namboku line), be sure to visit koishikawa korakuen it’s just a couple of metro stops away (open 9-5 near iidabashi station) it makes a great combination for a truly Japanese experience.
Stayed at Homeikan, Tokyo
