I could not find any evidence of wifi being available in the apartment. No router anywhere, nor wifi access information. Host did not know the network name and password.
Overall cleanliness of apartment could be improved. As a guest, I don't usually expect to find half-consumed products in fridge.
One simple, cheap improvement for guests would be an electric fan.
Toilet clogged late at night on second night, I was forced to go to a hotel. I had to contact AirBnB support to get reimbursed.
Host used a third party "conciergerie" service to handle basic guest contact. I found that experience disappointing, as they could not handle problems like wifi and toilet.
