Cassandra and Mikoto were great about communicating with us. Responses were excellent and they even provided some recommendations for our late night arrival the night before checking in! The check in process was really easy and self check in made it really convenient for us to show up when we were able to and not have to be on a schedule. Same with check out. Everything is well labelled in the apartment and the guide book left for guests is really nice. Wifi worked well.
The apartment itself is great. It is a studio and the main area is quite large! In addition, there is a large closet with tons of storage and even some board games. The shower is great -- good water pressure and lots of space (and a deep tub!). As pictured in the listing, the beds are two slightly larger than twins put together, which can be a bit tricky given the wood floors (if you or your partner move around a lot while sleeping, so too might the beds). Otherwise, the beds were comfortable and the bedding was cozy.
The neighborhood is very nice and close to a great grocery store and convenient stores. We didn't use the nearest train station at all, but it was just a five-minute walk. Instead we walked to Shibuya every day and then around from there. The walk to Shibuya is a nice 30 minutes. It's also a nice wander back if you enjoy the streets and back streets of Tokyo like we do! We would definitely recommend Cassandra and Mikoto's place. :)
