Margaret is an excellent host. The place looks exactly like in the pics. I stayed at her place because I was relocating to Dublin and Ranelagh is one of my favourites areas in the city.
Margaret is very warm and she'll be there whenever you need. It's great for solo travellers. The kitchenette is very handy and the rooms are big, and even though the bathroom is shared, you can notice is always being cleaned.
I would totally recommend staying at Margaret's. Specifically for young professionals who are relocating or looking for permanent accommodation in Dublin.
