The room looks exactly like in the pictures: cute, warm and cozy. We arrived in Dublin in the late evening, but luckily the host is very flexible with the check-in and kindly waited for us even if it was pretty late.
We never met Teresa in person and had little to no contact with those living in the house (we actually couldn't figure out who lived there and who was just visiting).
The house isn't far from the city centre and you can get to the main attractions in 20 minutes by bus, but it isn't definetively within a walking distance.
Overall, we had a pleasant experience :)
