> The best way to find info on where to live in Barcelona is the LIVE alumni network.
> The well-know airbnb.
> www.erasmate.com focuses on (international) student-to-student housing for short term periods and can be used for free by students.
> It might not be a good idea to rent an apartment without seeing it in advance. It is better to see it, know what appliances it has, check if the area is the most convenient for you, how close is from the LIVE venue, from the down-town, know who is the landlord, which other room-mates are in the apartment, if there are constructions nearby, if it is an apartment with a lot of natural light or just the contrary, if they are old flats without central heating, if it has a nice balcony or a terrace, if it has wireless, etc. All these aspects have to be checked before reaching an agreement.
> Barcelona is full of apartments for students and sharing an apartment with others students (from LIVE or not) is the best way to get integrated in the great university life of our city. Usually one person rents the flat and searches for the flatmates.
