From airport you have 3 options to come to ParisBy Bus It cost 17 euros per person and it takes usually 2 hours minimum (depending of traffic jam and waiting time) I do not think it s a good idea to come to Paris by Bus from the airport if you are more than 2 persons as the cost will be almost the same than in taxi. And remember that the bus will not come to the apartment. After your arrival by bus in Paris central you will have to take a taxi or metro or bus to finally arrive. And remember that you will have luggages. Luggages in metro is not easy.By Taxia taxi cost 55/70 euros depending of traffic jam and time arrival and you can be up to 6 people in a taxi. To make it simple : there is traffic jam from monday to friday 7h00 am to 10h30 in the morning and some traffic too after 5 pm at certain period of the year.There is no traffic on saturday and sunday.BY TrainIt s called RER. iT It will cost you 10 euros per person and it will take less than 1 hour to arrive in central Paris and then you will finish by Metro.And remember that you will have luggages. Luggages in metro is not easy as you have to walk and climb stairs.
