For the price point it's a pretty nice place! There are several apartments and the one I got wasn't 100% the same as the photos, which was a bit of a disappointment - but it was close enough.
The good: There is a 24/7 store about 2 mins away. There is a bus 4 mins away and 2 different metro lines 8-9 mins away. The area is quite calm and quiet. There is a washing machine and a way to dry your clothes as well, a sort of "dryer". The toilet is separate. There are other amenities such as water cooker, detergent, microwave etc.
The bad: This is personal, but one bed is way too soft, the other is hard as sh**. The room is very small, and more than 2 people would be tough. The fridge is between cold and freezing - some of our food/drinks got frozen over. The towels kinda suck (very thin), but get the job done. Only 1 toilet paper roll left for use, but it's see-through thin and the toilet is the washing one, so it's not at all suited for the toilet.
All that said, it's a nice little area and there are some really cool shops nearby, it's about a 15-20 min walk from Ueno in one direction and Asakusa in another, so if you're a walker it's in a really great spot. You have all you need and there is an AC in the room, both for heating and cooling.
