Arianna was very flexible and friendly since the beginning. She waited for us to arrive, gave us lots of recommendations, was very well prepared (maps, plug adapter, flyers). She left breakfast (eggs and bacon) in the fridge and gave us the possibility to carry the mobile WiFi with us during our visit to Dublin. The apartment is nice and comfortable. There is another room for guests so you may have to share the bathroom with another couple.
We are really happy and our expectations have been exceeded.
