Peter is a true host. If you want to be left alone to do your own thing, Peter's place might now be the best fit for you. If you, however, are looking for someone to interact with you, welcome you with scones and tea, provide you with suggestions for things to see and do, then Peter is the man for you!
The location is not in the city. In fact, it is about an hour outside of Dublin. But, in my opinion, it is a good location if you want to spend time in different places. My family and I spent one day in Dublin, one day in the north at the causeway and in Belfast (around 2.5 hrs in each direction driving) and on two other days, we saw Newgrange, Tara, Trim castle, Loughcrew Cairns, and the monastic site at Kells.
Peter also spent some time showing us his farm and he explained many things about the Boyne valley by taking us up on a hill and showing us the locations of various important sites. It was so helpful to really see it all right in front of us.
