Really good stay in Dublin. As promised the apartment is well located, next to the Guinness brewery and really close to the city center.
We arrived pretty late due to a delayed flight (11pm) and still had someone to welcome us (thanks Nico). We didn't meet Christian however the person who welcomed us was friendly and helpful.
We also had milk, coffee, bread, cereal, etc available when we arrived which was nice.
I definitely recommend this apartment.
