Super cute apartment in a great neighborhood! Hiroo has cafes, bakeries, cute bars and commercial streets. The supermarket is great, with helpful signage in English, (though it's a bit expensive) - there are also lots of 7-11's and a Lawson for last minute things.
The apartment itself is immaculate - spotless & clean - literally looks like its never been lived in, including the inside of kitchen appliances.
Unfortunately, we didn't meet the the owner as she had a family emergency, but sent 2 friends to meet us (though our flight was delayed), they took us through the space. Very kind.
My husband has travelled a lot in Japan on business, so I was prepared for a small space, and this is large compared to many others, however small yet efficient and stylish. I would suggest this place for a couple or 2 people, the extra bed upstairs is in a cubby, and def not for kids.

Owner also has a large binder with maps, Time Out Tokyos, and lots of info on Tokyo, including a hand drawn map of the area and restaurants - wonderful and thoughtful detail !

The only issue we had had to do with us being there in December - very cold. The apartment has an A/C heater unit both upstairs and downstairs but the heat element is not very efficient, as its mounted on the ceiling.The flat is made of concrete and has many windows, little insulation. Cold! We totally appreciated the heated blankets on the bed and couch : ) Bring some polafleece though! hahah...
Yume is very communicative, which was a relief, as Japan is quite far away, and you're kind of putting your faith in Airbnb (thanks, Airbnb!!).
Thanks Yumi - we loved out trip!!
