I've stayed in many AirBnbs all around the world, but I am very surprised to say that the absolute best value per euro was by far waiting for me in the field in Ireland!
The cabin itself is cosy and a level of comfort I was expecting without any disappointments, but the amenities were quite a surprise! The shower in the morning was really refreshing and in a modern gym-changing-room style part of the property. And there is a very cosy common area.
I was expecting to "rough it" by staying in a field, but it turned out to be a very relaxing stay! Being so close to Slane castle is a huge plus of course.
