Updates to Half An Hour From Paris

Parc de Bagatelle, p. 121
The ‘Pont de Neuilly’ bus stop for the 43 and 93 has moved to the other side of the main road.
Revised text:
Take ‘Sortie Avenue de Madrid’ from the Pont de Neuilly métro. The Avenue de Madrid is opposite the fountain in the middle of the road, with the Crédit Lyonnais bank on the corner. The Pont de Neuilly’ bus stop for the 43 to Neuilly Bagatelle and the 93 to Suresnes is a few steps after the bank, on the same side of the road. Take either bus and get off four stops later at ‘Place de Bagatelle’.
The Casino supermarket on the other side of the road when you get off the bus is now a Franprix.
