We had a lovely stay at Teresa's. The check in was easy. Teresa and her husband welcomed us and explained everything. The room is very cozy and warm. She gave us a lot of information on how to get to her place and about Dublin and the public transportation. There is a bus which takes you directly to the city center. The bus stop is only 100m away.
Everything was very clean and she offered several breakfast options (bread, cereals, tea, coffee). We would definitely recommend staying with Teresa.
