The short version

Based on about 290 recent Google reviews of this desk after exclusions (roughly 137 with text, covering about two months), most ratings are very positive for fast, friendly counter service and clean, newer cars. However, a sizeable minority of written reviews report bookings cancelled or repriced over card rules, post-rental charges (fuel, cleaning, damage) and insurance or extras added at the counter, plus waits of 30 minutes to 2 hours at busy times. Web evidence is mostly older or undated but broadly echoes these complaints.
