Unforgiveable: After I had paid the full amount to AirBnB, the host asked me to pay him directly too, against all rules; AirBnB strongly warns not to do so. This looks like a scam. Had I done it, I would have paid double and probably not got my money back.
From the bathroom comes a horrible sewer stench that permeates to the entire flat. In the bedrooms, sleep is disturbed by something outside, continuously rattling in the wind. The flat was superficially cleaned but if you look closer you find a lot of caked-on old dirt: major cleaning is urgently needed. Two of the 4 towels were lying crumpled and stinking: they may have been used by previous guests. No towel in the kitchen. Living room: minimally furnished, nothing done to create some atmosphere. TV: does not receive any channels. No user manual for TV, wifi, appliances, etc. Several lamps did not work.
Conclusion: the host did not make any attempt to make guests feel welcome. The place feels dirty & repulsive. We left a day early.
