In Ibiza everything is expensive. We are actually of the cheapest options you can get in airbnb!!! Maybe when you exchange to USD everything seems expensive- we charged much less than a taxi to take u to the airport and it was 6 am in the morning when we drove down there, you should be grateful!!!!! If not best if you would have taken a taxi....would have been even more expensive, you asked for me to drive you down and u agreed with the price. Bus stop works fine, buses pass every 20 minutes, we have had people using the bus to move all around the island and all has been fine.... you just missed the stop and went off too far... take care. love.
