The clue is in the title.
The cache is hidden a short walk from Érliget train station and is easy to acces by car and by walking. It is a small, plastic airtight container big enough for small swag.
The owners of the house opposite know about the cache but be careful not to turn the place upside down as they might whack you in the back with a shovel! Just kidding! :D If you are stuck you may get some information from them. (No.32)
