As a last minute booking we manage to get a place at Grange Farm.  We told the owner we had been before and asked if we could arrive early on the Friday morning as I work nights. This was fine and I got there and set up.  You don't see the owners much but I heard other people needing assistance and they got it.  The toilet was well stocked with loo roll and had hand wash.  Although it is near a busy route to Matlock for motorcycles it didn't really bother us.  We find it a relaxing place and to our surprise the price has not gone up any.  I would agree that the entrance is a little tight and suggest turning right in and not left. If your not sure go and ask the owner it will save any damage.
