Great little spot close to Yoyogi and Shinjuku stations. It's also right next to a park, tucked into a residential street so it was very quiet. It's a small space like you'd expect in the city, but the space is used very efficiently, and the appliances all worked very well to keep things comfortable. I was impressed that there was a washing machine! There's also a great tsukemen spot just a block away.
One thing to note is that there is no closet or storage space, so it's best for folks who pack light.
Overall it was perfect for spending a few days exploring the city. Sayuri was very responsive to my messages and clear with instructions.
