One time I had a vacation with my family in another city and my family rented some suspicious and not really good looking apartment and all the way to this city I was telling that they probably gonna drop us off with a complete silence leaving us w/o a roof under or heads...SO GUESS WHAT When my mom asked me how I knew we shouldn't trust them I told I viewed reviews from other guests on youtube, their website and the like. The funny thing was that the reviews of people from YouTube were their very own which means no one could monitor them and they were pretty honest when the reviews on their site were written by the owner of this whole business and as one can guess it'd be a flattering lie to fool their future clients. Moral of the story - sometimes it's worth being a lump of panic and suspicion like me to prevent surprises and fraud like this.
