There may be an affordable way for you to do it. You rent a basic apartment for 3 for 4 months. This apartment should be located away from the ocean (where the rent is much lower) but within safe bicycling distance, say within an hour. You can find rentals online, network with people and you may be able to find something suitable for you. The bicycles can be rented or even purchased and sold when you leave. This will keep you in good shape, enhance your appetite for good seafood, you'll sleep better and it will keep your transportation costs low. This 3 or 4 months stay it may cost about the same as if you spent 3 or 4 weeks, or less, near the ocean, with a car.
