Looking for a big room in Lisboa for two months

Hello, Me and my friend- Ana will come from Cracow (Poland), to Lisbone for an internship which will take a place in Sao Joao da Talha so that we are looking for a flat with good connection to that village :)

We want to share a room, so it has to be big enough for two beds.

We are arriving 21.09 and we will be leaving 05.12.2015

We are not stereotypically party-hard erasmus girl, so we will not disturb you .) we want travel around the Portugal during the weekends as much as possible so we usually we will be out of our place, but a few friends want to come and visit us for a weekend.

For now we can communicate only in english, we are learning portuguesse but we are not communicative in your language yet :)
If our language and our guests are not a problem for you, please let me know :)

We are not looking for luxuries flat, good price is more important than our comfort :)
