I was being a visiting scholar at DCU. Cynthia's place is about 15-20 minutes walk to DCU and using bus 4 or 13, it will be about 5 minutes' ride. The bus stop is very close to the apartment. There are supervalu supermarket, pharmacy, public swimming pool (single entry costs 7 euro). The best thing is that when you need to leave, there is a shuttle bus (cost 3 euro) just downstairs. It stops at Travelodge hotel to pick up guests actually but it is also open for the public to use to go to airport. Anyway, it is a very nice stay. Thanks.
