I went ahead and tried Easybus this time. I didn't prebook it since it was hard to know which bus I'd take. They run every 30 minutes on the hour and half hour. Lowest price offered online was about 2 Euros. I've seen it up to 8 Euros.
Had my directions - Terminal 2F, arrivals level. We wandered around looking for it for a good 30 minutes. We asked for help twice and both times were told we were in the right place. But there is no signage whatsoever. The second person we asked for help told us to exit through Exit 5 and so we did but there was just nothing to indicate Easybus went there. We found 3 other people looking lost and they were also looking for Easybus. We all stood around for about 20 more minutes and then, miraculously, the Easybus arrived at :46 after the hour.
Driver was fine...charged us 10 Euros, which suprised me, but I was wiped by that point. Probably wouldn't use it again and DEFINITELY wouldn't use it to get to the airport. If you decide to use it, just exit door 5 and wait there.
