Very bad!
I rented 2011 MB B class. They contacted me to change the car to VW Golf 5. Both small cars. Good for Albanian parking and travel to Corfu.
I got 2006 MB C class car. Big car. Higher ticket price. Hard to park. Takes A LOT MORE PETROL!!!
Key battery didn't work. I spent a lot of time time find a place to change the batteries!
Their answer were: MB C class is "a good car"!
Keep away from them!!!
