Well, if you are going to stay with these lovely people you are in for a treat! Carolinne, Jose & Maria are a really welcoming, friendly and hospitable little family and it just felt great to be with them. The room is comfy, cozy and as described. There's a good shower downstairs provided for guest use and also a huge kitchen / dining area (and even a little cupboard) available to guests which was great. The neighbourhood is reasonably pleasant too - there's a local park with good play facilities nearby and Crumlin is easily accessible from Dublin Centre by several frequent bus services which run into the later evening.
And lastly (but by no means least!) there's the super-affectionate La La the puppy - she's keen & 'full of beans' but if you are a dog-friendly person you'll fall for her just like I did ;)
So all in all, go & stay there!
