It's a good Airbnb and the host communicated well. however there is an obvious issue with damp in the apartment with a strong smell of molding damp, presumably due to the complete lack of any passive or flow through ventilation, i.e there are no operable windows and the only ventilation is achieved using a noisy manually activated fan.
this is a failure of the building's architecture and is therefore hard to pin on the host, however considering this issue the apartment is rather over priced.
I think it is bad hosting to not pre warn guests of this issue prior to booking as I could easily imagine some guests being unable or unwilling to endure the smell once they arrive. I noticed some improvement by leaving the bathroom and lounge extractor fans on continuosly. it's a shame to have to report this in the review, however the location is great and the furnishings are comfortable. the internet is also very fast.
