After arriving I messaged the host requesting to extend my stay. Messages were not opened and instead I was informed on my checkout day that the additional days would be much more. My original cost per night was $24 at the time. On my checkout date, he spiked the room price to $42 a night on the app and informed me “it’s okay I can give discount”. It was not a weekend, holiday or any reason for this price spike other than to take advantage of an opportunity he saw.
