If you’re feeling flush — very flush — then the Penthouse Suite in one of Paris’ most famous hotels, the George V, might just be the ticket. At $30,000 a night, the private terraces offering sweeping views across the City of Light are guaranteed to astound, but it’s the bathroom that really impresses. Floor-to-ceiling marble, extra-large walk-in shower, steam room and sauna and an impressive infinity bath (almost a mini pool) with underwater jets and a relaxing chromotherapy (colour therapy) system, so that you can match the colour of the water to your mood. fourseasons.com
