The Mercedes Viano we originally requested was swapped for a Volkswagen Multivan. It drives like a bus, incredibly noisy and has horrible sound insulation! It's extremely uncomfortable to sit in. The front layout is like a truck with a two-seater next to the driver's seat, and the rear seats cannot be adjusted. There's no storage space at all, and we couldn’t even figure out where to put a cup of water. They claimed it was an upgrade, which is ridiculous! I will never use this rental company again. We spent over 10,000 on this trip and were expecting the comfort of a Mercedes, but ended up with nothing! Terrible!
