Very comfortable, clean, and modern apartment. Room is spacious and has a small attached bathroom with a shower, toilet, and small sink (the kind that's integrated with the toilet cistern). The host is easy to communicate with and included thoughtful details like providing two pillows with different amounts of firmness. The kitchen/living area is just outside the bedroom.
The neighbourhood may look old but is generally quiet and very safe. There are convenience stores, drugstores, and eating places located nearby. The apartment is a short walk from Heping East Road (和平东路) which has many buses.
As others have mentioned, the apartment is on the fourth floor (stairs only) and the room door is frosted glass so light can come in. But I found those small inconveniences compared to how comfortable the place is.
