Hello, if you are interested in doing an internship with an Erasmus+ grant in Dublin you should read this post where I will talk about the experience of the first weeks and how it was.
The first place where you will probably stay is a hostel, meanwhile you will be searching the accommodation where you will live. The amount of time involved may be variable, but you should take your time to find a comfortable place to live as you are going to stay there for long.
It is hard to find accommodation in Dublin, you will have to search a lot and talk with many landlords before you get it. Take it with calm, you will find the correct one. The accommodations are normally very expensive so you should come prepared to spend a lot of money on it.
