We are visiting Dublin for the first time this summer, staying in Ranelagh, just south of central Dublin. Our place is near the canal. As we love walking around the places we visit, we want to know, how is that area? We've been told it's maybe a 20 minute walk up to city center through St Stephen's Green, which is fine, but we don't particularly relish the idea of a 20 minute walk through any sketchy areas. What say ye? Thanks!
