FOR BUSINESS - Le Bristol in Paris has a wonderful 18th-century decadence. It's a great location and good place to network, and it would make an ideal base for shopping. The rooms are spacious and airy with fabulous marble. Another big plus is the fantastic rooftop swimming pool - it's like a galleon. The grand restaurant is a wonderful place to have breakfast.
The service is impeccable and discreet. My brother and I are business partners and quite often share a room to save money. Once, my husband decided to join me for a night. My brother told the staff that another man was coming and he had to find somewhere else to stay. When he came back next day they were very confused.
