I stayed here for 4 weeks for partly business trip. The location us Super great -- close to Chuo Line Asagaya station and many, many local shops, restaurants, and bars as well as conbini and laundromats. The room is clean and bright with lots of windows. It was very convenient to have pocket wifi, kitchen sink, bath-shower, microwave, table and chairs, hairdryer, fridge, etc. One big problem I had was noise from the bar downstairs. They're open until 4am but there to close until around 6am and played dance music loud, which beats came through the floor and bed. They kept me from sleeping many nights, to the extent I called the police three times. I discussed this issue several times with Kimmy and Dee. They contacted the bar owner twice, were apologetic for the bar to continue turning back music, and eventually offered to pay me to stay in a hotel. I couldn't pack up and relocate as I had long business meetings scheduled. So I endured the noise. It sounds to me that the bar isn't owned by K&D (contrary to the review by another renter). They said they'd arrange soundproofing after I leave, so hopefully this problem will be resolved for future renters. To me, the fact that bars can operate until so late and make loud noises in non-business districts is ludicrous. I'm a Tokyo native (living in the US) and never knew this isn't against the law. My friends in Tokyo were shocked as well. Drunks come out to talk loud on the street. The bar seemed to get busy and loud after midnight. Considering this fact didn't appear in older reviews, but the person who stayed before me in April complained, I assume the bar changed the operation since the Covid regulations got loosened in April.
Other than this issue, the place was wonderful. I feel torn to give 4 stars instead of 5 as the problem wasn't caused by K&D. But because the noise issue dampened my stay, wasted a lot of my time, and deprived me from needed sleep, I have to report this and rate accordingly.
Note that aside from the bar noise, the room faces a busy street with lots of traffic so street noise and ambulance sirens are not avoidable. To me, that was nothing compared to the bar noise.
A couple minor notes: The bed seemed old. I could feel springs. A/C seemed weak but I needed only to dehumidify for a few days so I'm not certain.
