We spent three night's at Linda's house and enjoyed it a lot. Linda is a really friendly and helpful host. She told us a lot about the city life and recommended us the best pubs and restaurants, which really was worth it.
The location of the house is also really good. It's between airport and city centre. From Airport you can easily take the Bus Line 16, which takes about 25 minutes. To city center we mostly walked (about 25min).
We really recommend Linda's house to everyone who wants to spend some days in the beautiful city Dublin.
