If you're looking for a place in Tokyo, I can't recommend Robert's place enough. I never thought I'd enjoy living in Tokyo, but Sakurashinmachi is such an amazing place, and Komazawa is fantastic! It doesn't feel like you're living in Tokyo, but you're 4 stops away from all of the conveniences! I was here for 3 months while I was taking care of personal matters, and I've completely fallen in love with the area. I'll definitely be back.
Honestly, if you're struggling to find a place to stay, look no further for an enjoyable time here in Tokyo!
