We rented a room for three nights in Helen's apartment, as it was nearby family we wanted to visit. Excellent choice. Keys were available 24/7 from a concierge; our room and bathroom were roomy and fully equipped; kitchen and living room (with a fantastic view of central London) were continually available for our use and pleasure. Helen was home for one of the evenings - very gracious and accommodating - as she retreated to her room she made us feel the apartment was more ours than hers. The location near the Olympic village provides plenty of opportunity for leisurely strolls, while public transportation had us anywhere in central London within the half hour.
