Ireland is a beautiful country. It is filled with gentle slopes, beautiful landscapes, and breathtaking fields. There is a reason why there are so many famous Irish poets.
That being said, Ireland is a country that is rapidly becoming a multicultural hub. With this, there are growing tensions about the number of immigrants in the country. This has led to outbreaks of racism, discrimination, and violence. Marie and I felt the tension while we were there. It dissipated some when they found out that we were Americans (and planning to leave soon). I'm not saying this to discourage anyone from going, but it's a good idea to be aware of who you are and where you are.
Irish men can be very direct. This can be refreshing on a first date, but it's a little jarring when you're walking home at two o'clock in the morning. I also saw a large number of the "sensitive artist types" in Ireland, which I love. There is a vibrant art and cultural scene in the major cities and sometimes even in the countryside.
Go forth and find your Ireland.
