Terrible. A really expensive way to not sleep and be very uncomfortable.
Unfortunately this flat sits on a busy road used by cars and buses at all hours. The noise from the road prevents you from sleeping, unless the windows are closed when it becomes bearable.
However, the flat is poorly ventilated and becomes extremely hot in summer. There is no air conditioning so it is extremely uncomfortable unless the windows are wake are kept open.
As a consequence, after a hot and uncomfortable day in the flat you are left with are choice of sleeping in unbearable heat or being kept are wake by traffic.
I requested a refund for my remaining days after two days so I could find somewhere else to stay. This was not granted by the host.
Not an airbnb that I would recommend.
