Price not an issue. Need to be on or near the malecon.
If money is not an issue, there is a beautiful city north of La Paz called Loreto. If you like being secluded from the world I advise you to stay at a hotel called Villas del Palmar. This hotel truly makes you feel relaxed with super calm warm water and a really nice coral reef. A bit on the pricy side but it is well worth the stay. about 5 years ago
