The unit and location was perfect for me. I loved the quieter neighborhood vs. other, more busy cities like Shibuya or Roppongi, but still close and easy to get to those areas. It was right along the Meguro river and the riverwalk area was just great to walk around - tons of local shops, cafes and restaurants. Also close to the huge, 4-story starbucks reserve roastery and Don Quijote discount store. Because the train stop is within a 5-minute walk, you do hear the train, but that didn't bother me at all. The place was cozy and had everything I needed for my stay.
Riko-san is a wonderful host. She gave me great recommendations for Christmas activities around Tokyo and was always very responsive and helpful whenever I had a question or needed anything.
I highly recommend if you're a solo traveler. This may be a bit too cozy for a couple unless you really like snuggling together when sleeping or are okay with using a mat on the floor as well as the double bed.
