Car rental

Has anyone dealt with Easy hire/car rentals in Lo Crispin,don't seem to be able to find any revues about them.

We hired from them, or at least a company with the same name, years ago. Car had quite a few dings. It was cheap, but when I looked another time they were almost the same as the big boys. I would suggest looking at rentalcars.com, but Magnum in Algorfa are good, and pickup and drop off is easy.

Does anyone Know if it is legal to park twelve cars in the street on a residential estate while running a car rental business from a private house and using the road as a parking lot?

Depends if the property is registered as a business
The cars can be parked on any public road as long as they are legal in Spain
