Dublin City University is a great place to study and the people are very friendly.
The international office at DCU is phenomenal at what they do and are always ready to assist you in whatever your needs many be. Yet, when they don't have the answer, they are very helpful in guiding you in the right direction as best they are able.
DCU campus in Glasnevin is very safe for students, whether day or night. The Student Union and many societies within the college continuously put on events so you're sure to meet new people and friends in no time.
My programme was very rewarding to undertake as lecturers/professors were always helpful and offered guidance when asked. The classroom environment in all my modules/classes was wonderful. There was constant feedback and communication between the instructor and the students, often discussing topics academically where debate was encouraged. You very much get out of each module/class and programme what you put into it.
DCU has a decent gym, great swimming pool and indoor/outdoor locations for sports and activities which we frequently disposed of. Apart from the big canteen/cafe, several buildings have smaller ones that make it easier for everyone to get food during the day. There is also a local Spar where you can get groceries and visit their delicious deli where you can get all kinds of sandwiches, rolls and other things (the chicken fillet baguette and the breakfast rolls were my favourite!!!)
I would definitely encourage you to attend and experience it for yourself.
