We rented a motorhome and the experience was very disappointing.
First of all, they make it very clear that the motorhome must be returned in perfect condition: clean, with empty grey and black water tanks, a full fresh water tank, and a gas cylinder. They also charge €50 for cleaning and then expect you to return it spotless.
But the rental company delivered the motorhome:
Without gas (neither the refrigerator nor the heating worked). Not a drop of gas left; I had to go buy a cylinder as soon as I picked it up.
Black water tanks completely full.
Grey water tanks full, even leaking onto the road.
No fresh water.
In other words, in completely unsuitable condition.
This forced us to lose a large part of the day:
stopping to buy a gas cylinder
finding places to empty the grey and black water tanks
managing everything they should have delivered correctly
Even so, and despite having paid €50 for cleaning, they wrote to us saying it had to be perfect and with everything full and empty. We told them they had charged us €50 for cleaning, but that fine, we would leave it clean, but then they would have to refund the €50 cleaning fee. The woman who handles this said yes, she would talk to him since they had never charged that before and that obviously if we returned it clean they would refund us. We decided to do the right thing and return the motorhome in perfect condition:
clean inside and out (I left it in better condition than he had left it for me)
with a full gas cylinder
full fresh water tanks
empty grey and black water tanks
In other words, much better than when they delivered it.
When we requested a refund of the €50 cleaning fee (since the service wasn't provided upon delivery and we did the cleaning ourselves), they initially told us they would look into it.
However, they subsequently refused to refund the amount.
To make matters worse, I forgot a speaker in the motorhome, and after requesting its return, they haven't even responded and have kept it. I have a photo showing that I left it there, and they're ignoring me and blocking my phone.
In short:
They deliver the vehicle in poor condition.
They demand strict conditions from the customer.
They charge for services they don't provide.
And they don't respond to complaints or lost items.
A very unprofessional experience.
