Car pick up was very easy and desk agent was very helpful and friendly. Car was excellent and spotlessly clean.
Would have rated 5 stars but return process really let this location down. No staff on site in parking lot or any direction about what to do. One sixt employee appeared after a few mins and just gestured impatiently for us to move car so he could get into next one. No other communication from him. We then went to office and waited while agents dealt with new customers. We weren't acknowledged while waiting and after 5 mins asked if we were returning a car - was then told to "just leave the keys" - no explanation about €300 deposit return, any other info or even thanks given.
