Denis apartment was not very clean. There was mould and an old, used toothbrush in the bathroom and expired food, mayonnaise among others and broken bottles in the deep freezer.
The rest was okay. The hosts are very friendly, the area is good, there is much space in the apartment and we liked the very comfy bed and the birds and the cute, little dog.
I would probably not stay there again, but I would recommend it for people coming for a short stay to Dublin who don't want to pay to much, because the price is really cheap for Dublin.
If you stay longer you should know that there is no cupboard and no space to store your clothes.
