An ideal economical bolthole to get you into the Spanish way of life.
This may be the best chance that you have to buy a fully habitable property in a convenient location just a 10 minute flat walk from the town centre with less than 30,000€. Where else it is possible to buy a comfortable three bedroom apartment so close to some of the best beaches to grace the Med at the price of a new car, albeit a pretty good new car. Invest in a car and you can be pretty sure that you've made a loss as you drive it out of the showroom; with a holiday home the chances are far smaller of suffering a loss and almost infinitely higher for making a gain, plus you get to enjoy the holidays in your own place.
Depending on whether you're a glass half full or half empty type of person the lack of a lift to get to the third floor will either be a problem or a chance to make sure you retain your fitness. Either way it means that the running costs are lower; lifts aren't cheap to maintain.
