Just returned after 5 night stay. You should be aware of the hotel taxis that are not regular black cabs, have no fare meters and charge a range of fares based on how much the driver feels the paasenger will pay. After complaining to management I got 2 fares refunded that cost me close to $100 with the hotel cars, yet only $30 with London Black cabs for the return. The Hotel Concierges would seem to have some considerable kickback going on.
