I'm again doing research in London and have returned to the Staybridge Suites. It is really excellent: clean, excellent value, pleasant obliging staff, good breakfast with plenty of choice. The location is also great: while - unless one has an interest in the site of the olympic stadium - one would not come to Stratford for tourism, the Staybridge Suites is located close to a station with excellent links to all locations. There is also a mall next door, with Marks and Spencer and Waitrose for groceries for self-catering. For someone wishing for quality at a good price in London, this can't be beaten.
