The apartment was very clean upon our arrival. There are many steps which may make it difficult for some, but the floor level is listed in the posting. The "en suite" bathroom is actually one and 1/2 separate bathrooms shared with another small unit. There were no issues with sharing, and they were kept VERY clean. We couldn't keep toiletries in the shower (they were thrown out by cleaners, I assume) and that was our only frustration.
The bed is rather small, and we did not find the mattress comfortable. The studio is VERY bright and airy. It was stuffy when we first entered but opening the large windows quickly remedied this. Laundry was important to us, as we stayed for two weeks. There is laundry on site, but was often in use or on reserve (by storing linens in machines) by the cleaners. The neighborhood is great, grocery, eateries, coffee, outdoor market, Victoria Station, all in a few blocks. Neighborhood is clean and we felt very safe.
