21 year old hospitality student. Looking for apartment mainly in sintara or cascais or near lisbon.

Friendly and open minded, I do not mind any people. I would like to share an apartment with a friendly person for 3 months. My budget is 400 to 500 euros. I come from lebanon, beirut. I am 21 years old and a hospitality student. I am doing an Internship in Penha Longa resort. I also don't mind changing the city ( could be sintra or maybe Lisbon but not a clocation further than 20min to Penha Longa resort ).
