This taxi was booked for us by the hotel and we did not know at that time that it was not a local taxi from Amboise

 The taxi was in good time and was clean. The driver was pleasant and helpful

 We used this company while staying at the Novotel in Amboise. We only wanted to go from the Novotel to Amboise centre and on the outward journey we paid 17€ which seemed high compared with the distance.
When it returned for us - at the driver's suggestion - we were charged 27€. The reason given was that it was later in the evening (about 21:00 hrs)
We were not told the cost would be so much higher when the driver said to ring him for a return.
