The house is located in a nice neighborhood/area with good public transport by bus from/to Dublin Airport and the city center.
Teresa and Santiago are both respectful of their guests privacy, very welcoming and nice people. The dogs are friendly.
I booked the single room, which is small but enough for a few days stay. It has a comfy bed, nightstand and a wardrobe, no chair (which would have been nice). The curtains block all light during night. As others mentioned, no lock on the rooms door but I felt safe throughout my stay.
The bathroom is shared with the hosts and other guests, however during my stay I didn't see other guests and the hosts and I had a different bathroom routine. Bathroom could need some renovation.
The hosts live in their house and the walls are thiny so if you are a light sleeper bring some noise cancelling earplugs/headphones.
My stay at this AirBnb was pleasant.
