Well, in fact better than very good, I’d say excellent. The added value comes from the personalised service. We had 7 hours, picked up at Regent’s Park and taken to the Thames Barrier, calling at various riverside spots of historical interest and Barry was most knowledgeable and held our interest. He also knew the permissible parking spots and alleys which the taxi could squeeze along. This meant we got to see far more than if we had tried to cobble a trip together using tube and bus at a fraction of the cost but with stress, fatigue and dissatisfaction as unwanted added extras. Yes, I strongly recommend this way of seeing London.
