This place is not adequate for long term stay and is much smaller in relation to the advertised photos. It is necessary to give the right photos, for example, a) when the couch is open blocks access to door, b) the bathroom seems online to be big enough as to have a washing machine. Clearly, this wasn’t the case in what I saw, I barely could fit in this space. Also, advertise with clarity the conditions surrounding the apartment (underground, mouldy yard, exposed cables near the entrance, dilapidated apartment on the side/breeding ground of all sorts of insects and rodents, broken furniture in the garden, smell of mould as it is underground) that may be seen as health and safety hazards to those not used in such living conditions. As for the customer service, I understand that the working conditions in the Greek labour market are not the best and might cause a degree of resentment and a tendency to tell off people in order to get rid of them (or the problems they may cause) but please try to maintain the standards of customer service.
I have stayed with Airbnb in more than ten countries in the world and it pains me to say that this is the worst experience and unfortunately in my own country of origin. What a pity!
