I will provide a detail review because I believe in accuracy and fairness, and after staying two weeks at Ken's apartment.
The place has a MOLD problem. Throughout the shower area, there is mold present. Others have expressed in previous reviews the mold issue, and the owner has not fixed it, while saying he will.
There is a lot of mold in the water faucets as well which is very unhealthy.
When we got there the ACs was not working properly and was slow to cool the rooms. Turns out that the AC filters were clogged with thick layers of dust. We have to find that out. Ken fixed it once we reported it. Yet we reported the mold and was never fixed.
Also the two bathroom sinks were clogged and would be filled with water that was very slow to drain. This was also reported but ever fixed.
The mattresses are quite uncomfortable and should be replaced. The sofa as well, quite uncomfortable.
In one of the rooms the wallpaper is pealing off. The floors were very dusty. The house had an odd smell that lessened as the days passed.
MOST IMPORTANT - As Ken warns, you MUST be very quiet at night or the neighbors will scream at you. This becomes a stressful situation as you have to whisper while in the house at night, make sure you are totally quiet when returning to the house. If you are on vacation, this is an unnecessary stress. You have to even deny that you are an AirBnB guest! I felt like if I was doing something illegal. Not cool!
Finally, the check out time is at 10am. Our flight was due at 7pm. We requested from Ken if we could leave the apartment at 1pm and he said no, even though there was NO incoming reservation (I checked). That was mean, as we had to leave in the morning while it rained, and the place is not very close to the station; definitely not as close as advertised.
Therefore, I do not recommend Ken's place for staying in Ikebukuro. Not until he truly fixed the MOLD issue, keeps the house cleaner, replaces the mattresses, gives maintenance to the walls, and fixed the legality of the rental place and the issue with the neighbors. Only then it would be an OK place to stay.
The price is not cheap, and one should not have to deal with these repeating issues. You might as well stay at a hotel.
Very disappointing, and I will not be returning to this location.
