23 year old student from U.S. needing cheap accommodation near UCD Belfield

I am a 23 year old Female international student from the United States. I will be studying at UCD Belfield campus in the Graduate Veterinary Program. I am pretty easy-going, but am very school oriented. My personality is very easy to get along with others, but I am quiet at first until I get to know you! I enjoy indoor and outdoor activities such as horseback riding, hiking, painting, and reading.

I would like somewhere cheap, i do not have a lot of money due to the school expense, and fairly close to the school. I would like somewhere decently comfortable, that is mostly furnished if possible. I will be starting in September and participating a full course or more. It would be ideal to move in a little earlier.

I do not mind families, roommates, or animals as long as I am able to study adequately.

I have never been to Ireland before, so any advice would be great!

Thank you!! -Chyanne :)
