Ichika’s place is pretty nice, and in a good location about halfway between Waseda University & Takadanobaba. About a 15 minute walk to either station (nishi-waseda is closer). The hosts are very responsive and help really quickly if you need anything. The place has everything you need, and is in a quiet area, next to a supermarket with lots of nearby options to eat. Good value for a pretty good location for long-term visitors. Maybe not an ideal location for a short-term tourist who is going to go to a lot of places everyday (in this case you might want to be slightly closer to a major subway station, but I would expect to pay more to be closer). Would recommend!
