We are extremely disappointed with the entire experience and Antonio as a host and were forced to leave 5 nights early.
As a construction professional myself, it is clear that there have been many corners cut during the renovation for all the utilities, specifically the toilet drainage and electrics, leaving us having to run away as we suffered 3 floods of waste & feaces water in the bathrooms and hall which has been a horrible experience for us and left us (4 guests) with no access to a bathroom for 24 hours.
It would seem as though the waste pipe is blocked (possibly with cement) which will require uplifting of the whole floor.
My hope is that this experience has taught you it is always worth doing a job correctly as it will cost you more later down the line. We also hope you fix these issues before you welcome any other guests as the current state of the property makes it absolutely inhabitable and unacceptable for business.
The only positive we could say is to mention the facility manager Jovi was of great kindness, he showed us support as opposed to the host (as Antonio cleaned his hands of the situation) and even mentioned how the host will not pay him for any of the extra work he had to do solving issues everyday which seems completely unfair and says a lot about the situation.
