I've stayed here a couple of times now, it makes a great base of operations for me in Tokyo. It's northwest of Tokyo proper, but most of my friends and things I do are on the west side, and the Ikebukuro station is very easy to navigate: Gates for all the lines are directly connected to the underground and the hotel is easy to find from the station (just look for Sunshine City and then Exit 35). The hotel is maybe a 5 minute walk from the station entrance, so is quite convenient, and its room rates are very good.
I like staying in Ikebukuro, as there are loads of little restaurants and bars near the hotel, as well as live music places that I've yet to check out. (Also tons of girls bars if you're into that and speak Japanese. I don't know much about that culture though.) The area has a very young vibe, and I find it very pleasant to stay there.
I initially found Ikebukuro and this hotel when searching for low-cost places to stay with decent room sizes now that I'm retired. This is cheaper than I could find in Shibuya or Shinjuku, and those places are just a few stops away on the Yamanote or Saikyo lines.
The rooms here aren't huge, but they're larger than many and the under-bed storage really makes a difference.
The staff has limited English, but Google Translate works well and there's usually someone on duty that speaks at least some English. I didn't have any trouble communicating at all.
Overall this is a great, very economical place in a fun area to stay in.
