I had a good experience at Beata's place. Bed was really comfortable, the room was amazingly cleaned and I really appreciated to have small amenities like a bottle of water.
In terms of distance, there are some things to be considered when you are not going by taxi or do not have a car (and it is raining): bus station: 8.5 min walk, supermarket: 9 min walk.
From city center, it can take from 25 to 40 min to arrive to the place depending on the traffic. In case you want to do one of the tours outside Dublin (mostly in the early morning, 5:00), there are no buses available and you have to take a taxi (around 22 euros with Free Now app).
Communication was fast when needed. And if you want anything, ask. Ask for things like wifi password or how the heater works, if you do not ask maybe you will be not informed.
Neighbourhood is quite and peaceful and there are some restaurants next to the bus station.
Overall, a good deal for the price compared to other places!
