Katakoto Inn was ideal for our stay. The room was very spacious. We had everything we needed and free use of the laundry facilities was a plus.
It is slightly further out from central Tokyo but only a short walk to Ogikubo for the JR/metro made it easy to get around. Ogikubo itself has plenty of shops and restaurants and there was a Lawson convenience store just around the corner from Katakoto which was handy.
Excellent value for money, would definitely recommend.
