I stayed at this location for roughly 7 days and I was very comfortable. It was very quiet at night. Its just enough for 2 people. Any time I had a question, Kimmy and Dee answered me right away. They provided pictures and great details on how to get to the location.
For those of you planning on buying the 3 day Tokyo subway pass, one thing to note is that the location is a 15 min walk from the subway. We actually enjoyed the walk and got to see a lot of the neighborhood. However, if you are keen on taking the JR to save time, it really is a 5 to 8 minute walk.
There are plenty of bakeries around the JR as well, which served as a nice breakfast for us (we highly suggest Saint Germaine) as well as a Starbucks at the station. This was really nice for us since we live in Korea where breakfast and quality bakeries are few and far between. Plenty of restaurants and bars in the area, but they arent loud and crowded. The neighborhood around the Air BnB is really cute. We went out drinking at one of the Spanish bars and had a great time.
Another thing to note is that the pocket WiFi, while convenient and free, was spotty. We didn't mind, but if you're determined to use Internet often (especially if playing Pokémon Go) you may want to buy additional data for your phone when the WiFi is out. It was great when one of us used it, but got a little spotty when the 2 of us where on it. Keep in mind, this pocket WiFi is free. Again, this didn't ruin our experience at all!
We will definitely book with them again!
