We had a very great time and nights in Federico's house, it was really nice, cosy and clean !
We particularly appreciated the breakfast, nicely prepared in advance every morning, it enabled us to save a lot of time, thank you very much :)
The house in located in a residential district, rather calm but a little far from the city center. Though, buses are not that far from the house, and the network is efficient.
Nice place to come while visiting Dublin :)
