If you've opted for a honeymoon in South America, there's nowhere better to start than Buenos Aires. Argentina's capital is like a more cutting-edge version of Paris, with elegant buildings, tree-lined avenues and pretty squares. The city's hottest area is Palermo Soho, the location of the Costa Petit.

This is not an all-singing, all-dancing hotel with room service and a buzzing bar: this is a secret bolthole with just four exquisite rooms. Here the beauty is in the detail - aged trunks, an old wooden dresser, a rose velvet chaise longue.

The main reception area also serves as a sitting room, breakfast room and library and there is a courtyard pool. The atmosphere is so peaceful and the service so personal, you feel as if you're staying with friends in their grand home.

Wow factor:
Swimming in a beautiful pool in the centre of Buenos Aires, without having to stay in a big chain hotel.

Flight time:
From 16 hours via Sao Paulo.
