Yes there is. And it is free. Some guests do try to watch movies on the internet. If you try to do this, you will most likely be very disappointed as the signal is not strong enough to allow this especially if many people are on the internet at the same time. The internet is really for checking email and surfing the internet and not for watching streaming videos etc.
As stated elsewhere, we do not have cable in our area so our Wifi signal is a souped up cellular signal. The villa is made of solid concrete reinforced with steel and so despite multiple signal boosters, the signal strength is not that of a T1 connection. T1 connections are not available in our immediate area. Please be sure to explain this is every member of your group to prevent disappointment.
