The inaccuracies begin with the listing name: it says 'Palermo house' when it's in fact in Colegiales. Ok, at least the host mentions it in the description.
What she doesn't mention though is that the photos are heavily photoshopped to make the house look extremely bright, light, airy and modern when in fact it's quite sombre, not as spacious, and the 'vintage' furniture is actually just shabby and worn down.

We soon discovered more obvious discrepancies:
two single beds instead of one large bed downstairs
some furniture missing (coffee table) or rearranged
the rooftop terrace looks nothing like the picture. The furniture was replaced with a cheap plastic table and plaid chairs
No carpet on the floor in the bedroom upstairs
Other flaws:
the toilet downstairs was broken - it didn't flush properly. Although the check-in lady said you could pull a string in the tank to flush, it still didn't work. They said it's going to be fixed the next day but we had to put up with using the toilet upstairs for the day.
it's really cold in the house in September because there are lots of windows and the frames are old. The AC can't heat the whole place.
it's just not as nice and cosy at it's presented
CLEANLINESS
we were horrified to discover piles of dark hairs in the toilet upstairs - the floor clearly hasn't been washed
then we found lots of dark hairs spread all around the bathroom walls. That was truly disgusting!
the floor on the rooftop terrace hasn't been even swept, let alone washed. There were traces of dirty shoes all over the place
Besides, I only noticed afterwards that the listing says there's 'Complementary cleaning twice a week', which I suspect is supposed to mean 'complimentary' = free. However, the check-in lady said she can come and clean for a FEE. (Which is fine, but why would the host claim otherwise in the listing?!)
The check-in was ok, although we had to interact with three people: the host herself on airbnb, some other lady on a messenger and the third lady who actually met us at the property. The latter doesn't speak English, which wasn't an issue for us but might cause inconvenience for other travellers.
On to the most 'exciting' part responsible for the lowest review score I ever gave a place on Airbnb.
We initially booked the place for a whole month because it looked great (in the photos) and most of the reviews were positive (don't fall for that). When we realised what the place is really like, we were desperate to leave and get a refund.
I contacted the host later the same day and let her know we were dissatisfied. She did not even offer to fix any of the issues or attempt to make it up to us. She said 'sure, you can even leave right now if you want'.
We agreed that we would check out at 10 the following day and submitted the refund request with airbnb. Since it was the first time we ever did that, we weren't sure whether we are eligible for a full refund or a partial refund, so we applied for the full refund just in case.
The host declined the request and explained we need to pay for 1 night we stayed. We didn't mind that at all and I submitted another request, this time through the Airbnb support (I no longer had an option of correcting my initial request). They let me know that they contacted the host and are expecting her approval on the refund.
This is where it gets really interesting (and outrageous) because the host keeps telling me that no one has contacted her. She tells me to cancel my reservation and threatens I'll have to pay for the time it's vacant but formally occupied by me. The problem with cancelling the reservation like that is that I would lose all the money (for a month's stay) and would not be eligible for a refund. Apparently that's what she was trying to manipulate me into. When I did not yield and when I shared my concerns about that, she told me I was being disrespectful.
Anyway, the next day Airbnb resolved the problem, as never heard back from the host, and we received a refund for the whole stay except for the 1st night. Thanks to that first night we stayed, we got to write this review which I hope you enjoyed reading.
P.S. Thanks to Airbnb support for quick and efficient help.
I do hope this situation will teach Carolina (the host) to be more accurate and honest, take better care of the property for her guests and be a better communicator.
