Extremely convenient, well-appointed apartment convenient to Ikebukuro and Mejiro stations. It’s almost a mile to Ikebukuro station, about half a mile to Mejiro station. There is a 7-11 around the corner (open late) with an ATM that accepts most US cards and has light grocery needs. There is also a traditional grocery store just last that if you want to do your own cooking. There were umbrellas available at the apartment for outings when the weather is bad. The listing rates this for seven people: We had four people in our party and for American sensibilities four is probably about the max US travelers should plan on. The washing machine works great; drying is line-drying on the balcony or using a drying function in the shower room. The apartment is a very typical Japanese apartment so come with those expectations and please come with those manners - walls in Japan are thin and if you laugh loudly or bang your suitcases around your neighbors will hear it and will not appreciate it. If you don’t have good enough manners to keep quiet in a Japanese apartment, though, you’re probably going to have a rough time in Japan.
For checking in, follow the directions in the info you’ll get after you register. The directions are very detailed but you must follow them exactly. After a few trips to and from the station you’ll know your way by heart.
The neighborhood is extremely quiet and residential; the closest restaurants are a several minute walk away. If you want a nice quiet area - this is perfect for you. (Assuming you can be as quiet as your neighbors).
