First of all- the communication with Catalina is very easy, she does everything to help one out. The check-in was also easy and the room is clean.
The thing is- you are sharing the house with other guests and it is quite like a flatmate situation- everyone has access to the kitchen/fridge and heating/water regulation. We did not meet Catalina, so depending on the other guests some areas (like the fridge) can be a little bit messy or the heating or warm water is not constant. If you are fine with this, the house is perfect for you.
We also could hear quite a lot from the kitchen in our room, but fortunately this was no issue at our stay.
The close neighborhood was all right, but if you are travelling alone, please be carefull of the general area and look out which street you take home from the city center at night!
That said, we still had a very nice day in Dublin.
