My partner and I recently had a bad experience with accommodation portal website http://www.amazingaccom.com/.
We booked a nearly $1000 a night house advertised as sleeping 12 people and having 4 bedrooms, one being a bunk bed room with 4 small beds and a "separate downstairs living area" that could accommodate a queen bed which would be available. This "separate downstairs living area" turned out to be hallway space off the garage, between the 2 downstairs rooms and the bathroom and there was no bed. So 2 of our friends had to sleep on the floor in this space, which, considering what we were paying was totally unacceptable. There was a strong gas smell coming from the external downstairs water heater also- calls to address this were not answered by anyone at the company and as a result we were unable to use the downstairs shower as we had no idea if it was dangerous or not to do so. The company offered us a small refund which my partner accepted, but was half what it should have been based on the fact that 2 people slept on the floor for 2 nights. The website has since changed due to our complaints but we were unable to reach a satisfactory settlement.
We rented another house nearby too- which had the longest, steepest driveway I have ever seen. This was not mentioned in the listing at all- seriously, unless you were reasonably fit, you could not walk up this driveway at all. My car barely made it!
My correspondence with Campbell Bevan at Amazingaccom.com to address this was met with rude arrogance and we will never deal with him or Amazingaccom.com again. If you do choose to rent from these people, be absolutely sure you know what you are getting as they were less than upfront with us.
