24-year-old girl looking for an accommodation in Matosinhos/Porto

I am a 24-year-old student from Estonia about to start my exchange studies in Escole Superiore des Artes e Design, in Matosinhos and am looking for an apartment for that period of time - starting from 1st of October 2016 and until somewhere at the end of May 2017.

I am looking for a place where visitors would be allowed as I have a boyfriend living in Lisbon and he might visit me every once in a while. Also, in case my family or friends want to visit me form Estonia.

More about myself - I am a cheerful spirited person with a healthy lifestyle. I spend most of my free time doing sports, reading or learning new things. I also like to do yoga. I believe I would be a good lessee because I am a very tidy and responsible person.
