This is not actually an entire apartment as marketed. It's a private room in a guesthouse, with a private bath. It does not have a private kitchen; there is a kitchen shared by all the rooms at the guest house. It does have its own tiny fridge. Didn't matter to us as we weren't planning to cook, but it's not properly marketed.
Location: great, if you want to be in Asakusa. It's an easy walk to the main tourist area/temple and transit. Not on the main JR Yamanote line though, which we did't realize. Still pretty easy to access via subway though.
Condition/cleanliness: It's basically as pictured. It's a large room with tatami mats, a small side table, and futons. We enjoyed the style, and it has a large closet for hanging and storing items. It was very clean. However, there is water damage to the walls and ceilings and rips in some of the wallpaper and window coverings, so it's a bit run down. The bathroom was perfectly clean, though.
Lighting: Very bad! One huge extremely bright overhead light that can't be dimmed. Way too bright and glaring to be cozy or comfortable in the evening. And that one light flickered wildly the entire time it was on. Totally unacceptable.
Noise: the building was quiet, but there were loud people in the street below all evening. Very unusual for Japan, which we otherwise found to be very quiet, even in other neighborhoods in Tokyo. Also, the window coverings don't keep the lights from the street lights out so the room stayed pretty bright all night. You want an eye mask and ear plugs here.
If they fix the lighting and add a cozy lamp of some kind, it would be a perfectly acceptable budget accommodation, as long as you don't actually plan to cook and expect a private kitchen.
