I stayed at this place for 8 nights. The room is very small. There's barely enough room to open one suitcase on the floor, but it felt cozy. Comfortable bed. The entire building with multiple apartments is owned by a Chinese woman. Shes doesn't speak English at all in person but somehow responds pretty well to messages (maybe via Google Translate). There are many Chinese people running Japanese style restaurants in the neighborhood. The rooms are like a lottery. You might not get the one you saw in the picture. Some apartments are worse than others. Most people there stay 1-2 nights, so if you are staying longer you might hear people moving in and out every other day from the second room. I was lucky and only had 2 people staying there for 2 nights each. The rest of the time I had the place all to myself. The room has very thin glass walls on two sides, which don't retain heat at all, so you will need to crank up the heater if you're staying during winter. There is no heating in the common areas (bathroom, toilet room, kitchen). It was always freezing when I stepped out of my room. The kitchen was full of clutter and a bit messy. Even though I was the only one staying in that apartment when I arrived, the fridge was fully packed with old snacks. It kinda looked like it could have been filled up over time by people who stayed there before me. The hostess provides shampoo and shower gel but no hair conditioner. Overall I had a good experience with this place. The only two big issues were that the hostess and/or her staff come into the apartment at least 3 times per day for who knows what reason so there's not much privacy and the worst part is that they leave the apartment door unlocked every time. I even came back late at night a few times to find the apartment unlocked.
At the end of my stay, the hostess carried my heavy luggage downstairs from the 4th floor, which was really nice of her.
