We were the only two on this tour, which felt a bit awkward at times, some of the info was very interesting and some was not. The guide knew a lot and talked non stop. The tour lasted from 9am till 2pm, we got off near the Chelsea market which we loved. The 12 seater minibus made it difficult to see the sights because the windows were low and seats high, we both had sore necks by the end of the tour.
