Sol-Mar is a Spanish car hire company, mainly operating at Spanish airports. It has offices at Girona airport and Barcelona airport, but doesn´t have any in Barcelona centre.
Sol Mar is a smaller Spanish car hire company, and most of their offices are found at Spanish airports. The prices are very reasonable and they have a wide range of vehicles on offer, from automatics to convertibles. Their airport office is a little further from the airport than the other car hire companies, but they offer a shuttle service from the airport to their office. It´s worth checking their prices as they can offer very reasonable rates, especially since they are open 24 hours, 7 days a week (with advance booking).
