Cozy room equiped with a wardrobe and a French-window to the balcoly but really small so a little bit oppressive on long term and with no access to a table, it is actually unpractical to eat when you don't want to go to restaurant or pub. Bathroom is quite big in comparison and fine. The flat is a bit noisy though with the water system just behind the bedroom wall and you can easally hear voices. If you have a light sleep, take earplugs ;)
The location in Smithfield is great with the red line at the foot of the builing and 20min walk from Temple Bar. The neighbourhood is nice and safe with some cafés where you can have lovely breakfasts (Cinnamon, Urbanity...) but the shapes of the buildings make the place verry noisy when parties are going on outside on the Park (I was there for Halloween...) and it could be verry upsetting when hypersensitive to noise like me.
I had a nice stay at Helena's who is a nice lady btw. I think it's the perfect spot for one night or two trip to Dublin.
