Le Club Accorhotels members are eligible for 20% off + 1,000 bonus points at any of the three Sofitel hotels in London until August 31, 2015.
The offer is valid for stays booked minimum of 15 days in advance.
You can access this offer on Accor’s website here.
Here are the participating hotels:
Sofitel London St. James
Sofitel London Gatwick
Sofitel London Heathrow
I have not stayed at any of these Sofitel hotels in the London area, but the Heathrow one should be very convenient for airport access.
