I stayed in Marvin's place with my boyfriend and we loved it! It's in a perfect location, you can reach all the main touristic highlights by walking. The place is clean and pretty, we had a really good time there. Marvin wasn't home, but his flatmates/friends were really welcoming and nice and they also helped us with tips where to go and they were always fast to answer. We'll definitely come back if we stay in Dublin again!
