The apartment is located northbound of the river that means just few minutes walks to the lovely temple bar district. However, it is not loud at night and you can find your rest easily to be prepared for whatever comes the next day.
The flat is really clean and thankfully the house has an elevator.
The host is such a friendly and helpful person, who gives tons of valuable recommendations. If I come back to Dublin, I'll never search for another place to sleep, already found the perfect one :)
