We had a comfortable stay at Niall & Grace's place and it suited our needs as we were staying in Dublin for a family event. Downstairs it's a big space and has a very homely feel so we enjoyed using that. The upstairs is a bit smaller but both beds were really comfortable and everything was spotlessly clean.
I did feel that the house needs a little bit of TLC as it was slightly tired in places and there were a lot of clothes in both bedrooms so there was no hanging space at all in the main bedroom.
Great location for accessing the seafront and for a short journey into Dublin City Centre.
