I have nothing but nice things to say!
Yume's apt is lovely, beautiful, well designed, interesting, convenient, and quite charming.
Some quick details...
Bathroom... has a luxurious tub as well as a shower with good water pressure and lots of hot water. Nice products and big for a Japanese bathroom. Only things to note: (1) it has glass doors, so if you need privacy, you can use the curtain and (2) the shower handle slips sometime - you can prop it up with a small bottle or similar.
Bedroom... tons of light. very lovely. Little balcony, full-sized bed (plus a twin bed on the third floor), very warm and comfortable room.
Kitchen... washer dryer is very nice to have, opens to living room... fridge stocked with some goodies, nice coffee equipment, very useful.
Living room... good TV and sound system, comfy couch, nice small desk for working, good closet space.
Generally, a great apt and one I would recommend to anyone!
