Apartment is located on the first floor of the building and right beside the lift which you'll be able to hear everything anyone says when they exit/waiting for the lift. It isn't that bad a thing considering the fact there isn't much activity but then again, it may not be the unit that everyone would be comfortable in.
The place is quite clean and bigger then some airbnb's i've stayed in when I was in Japan but there's still a lack of space I find. They put the extra bed in the closet which meant I had no space to store my luggage away & there really isn't anywhere for me to hang my clothes and had to live in the room with our luggage open. Well least the room is big enough for 2 big luggage to open and have some space to walk around.
There is only 1 aircon/heater in the room which makes the whole place cold all the time with exception of the room & the hot water in the taps takes quite awhile before they get hot.
