Jim's place is well located, only 10 minutes walking to the Temple Bar area and most touristic attractions.
For us it's ideal to spend the weekend in Dublin. Walking distance to almost everything, the room was warm (it was nearly 0 degrees outside and I was in shorts and T-shirt) and also you can grab some fruits, toasts and cereal if you want.
On top of that, we have met Jim and he's super nice and kind. He lent us an USB cable and an adapter, gave us directions for everything we asked and was very flexible with hour check in/out.
As it says in the ad, there are two cats you may bump into, but they are shy and we haven't even shared the same room with them. (If you are not fond of cats, you don't have to worry about it).
Overall, I think this place is well balanced and really handy for a getaway to Dublin.
