I joined Airbnb in 2011 and I make around ten bookings per year due to work and personal travel. This Airbnb experience was by far my worst. Firstly, the flat is managed by a company rather than an individual, which is fine in most cases. However, with this flat, there's seems to be a management team and local team. I spoke with Julia, Anastasia, Omar, Jurgen and others throughout my stay and as such the communication is slow and broken. I only got to know the person who was responsible for me, sort of, during my stay - Eduardo.
Two shower heads were broken and the water pressure was so weak that not even men could rinse their hair, let alone ladies. I contacted Eduardo numerous times. Finally the mechanic came on the third day of my stay to only first one bathroom, leaving the other shower head still broken. Although Eduardo and the mechanic promised to come back the next day... that never happened.
The first day, the sink of the shower stall was clogged and the water overflew. I had to buy acid on my own to unclog the sink.
Communication generally was slow. The only time it was really fast was when Eduardo tried to charge me for the airport transfers and the city's tourist tax.
The only positive side is that the flat is centrally located and it's clean (apart from the clogged sink).
Very bad experience. I would avoid at all cost.
