We booked the five bedroom house as featured here more than six months before our stay. We decided to stay here rather than a hotel (which would have been a similar price... £850 per night) so our families could be together with some communal space to hang out. The house is fantastic and worth the money.
HOWEVER... the owners rented three of the five rooms we had booked to other guests and instead gave us two completely separate apartments (in addition to two of the original rooms). This meant that our group, which included a number of children, were in three different places with three separate entrances from the street. In addition to this, and despite reassurances from the host, the two alternative apartments were nowhere near the same standard of comfort - dark apartments with small / uncomfortable beds.
There is no way we would have chosen these apartments had we known the details in the first place. We arrived very late at night off an 11 hour flight from the UK and because it was the weekend of the Mexican Grand Prix our options for alternative accommodation were limited, we felt that we had no choice but to go along with the situation. I have requested a part refund from the host but as yet he has not responded. I think it is shocking that this situation can happen and I will think twice before booking another Airbnb trip.
