I would say overall I would recommend this place, with a few caveats.
The pros:
The place is a very nice place overall. The location is absolutely excellent. You can get anything, groceries, clothing, pet supplies, stationary, liquor, public transit, you name it, you can get it within a 1 to 3 min walk. The best part about this place is the location. The subway to go anywhere is literally across the street. The decor is beautiful, the beds were very comfortable. The space is very big. The place looks like it was just recently remodeled maybe only about a year old after remodeling. A/C new, appliances new, everything new. The place is very quiet despite the loudness of the location (very much in the heart of the Okubo area). The host is very responsive, always answering emails within a few mins or 30 mins at most.
The cons:
The things that could improve is the lingering smell and some areas of cleanliness. The walls behind the kitchen sink and stove area were very dirty, the kitchen cabinet surfaces were dirty, the refrigerator surface was dirty. I wiped down all these surfaces with rubbing alcohol on our first day. The shower and bathroom sink smelled badly when we first arrived, but the host was very responsive and sent the staff in the very next day to clean the shower and bathroom sink, and they never smelled again (so just make sure they thoroughly cleaned the bathroom sink and shower before your stay). The bedsheets all smelled badly, only one set of sheets did not smell, so we used that one decent smelling bed sheet set. I believe the sheets were washed, but perhaps without enough detergent. The towels also smelled badly. We never used them. We bought our own towels on Amazon and used new towels instead. Lastly the entire living room area smelled badly when we first arrived. It smelled ok after we sprayed deodorizer on the couch and dining table benches, but we had to spray this deodorizer every 4 days to keep the bad smell away. It's likely that the upholstery furniture needs to be thoroughly shampooed. The cleanliness of the place is the only thing I would say was not good enough. Overall the place was clean, it was just a couple areas like the kitchen wall surfaces needed wiping down and the living room smell was off-putting, until we deodorized the place with spray (the host was very responsive and sent us deodorizer spray right away when I informed them via email about the smell). But other than this, the place is a very nice place and I would say I would still recommend it overall. Just be prepared to ask for deodorizer if they had not shampooed the furniture yet by the time you rent this place, and make sure other areas don't smell (and thus need a good cleaning, which they would happily do for you if you tell them).
