Remis to and from Airport
In the past five years I have used the remis services described by Aqualung below from the airport perhaps 15 times. (From the desk at the airport, not the elaborate service he is offering.) It is more expensive than the taxis, but I usually have a lot of baggage and the drivers have been very good about helping me get my stuff into the apartment building. I have used the remis service on Callao (roughly at Arenales) another 15 times to go out to the airport and it has worked fine as well. On occasion, I have used taxis and the Manuel Leon bus service and they were ok, too.
