I have stayed at this hotel 4 times over the last 6 years. Its getting a little tired now and I will look elsewhere next time. The twin rooms are very small and the room furnishings are looking pretty worn. It has over a thousand rooms but its a dumping ground for large tour groups.
The ONLY good thing about this hotel is its location. Situated just 5 minutes walk from the Ikebukero train station; a major hub for many lines. it is also only minutes from the huge Seibu and Tobu department stores. In addition it is located right next to Sunshine City, a huge shopping centre and it has a wonderful 24 hour supermarket across the road where you can buy the nicest freshly prepared food and heat it up in the microwaves provided. So if you can stand the rooms being small and on the dingy side; and you didn't pay too much, it does have advantages.
