We have a magnificent public car park right outside, so you can leave the car there for next to nothing and bring up all your luggage in a stress-free way. The old town is more problematic in this respect. When you feel recovered from your journey, you can move the car to our own parking space in the same block or drive to Migdia Parc, where there are often spaces available. This is a free unenclosed open air parking area, worth a try. It is a good 10 minute walk back to the apartment straight along C/ Barcelona (this is not the way you drive to it).
We have 2 parking spaces available, not included in the cost of the apartment rental, as many people do not need it. Do let us know if you would like to reserve a parking space with your booking. Neither space is suitable for 4x4's or vans i'm sorry to say.
(The useful car park next to the apartment costs 26€ per night (Oct 2016). Our own space is 10€ per night for short-term stayers)
