You will have different options for accommodation:
The most convenient option is the residence of the university, Vila Universitària UAB. We will help the students who wish to stay in the Vila Universitària. Some rooms will be reserved for the whole duration of the summer school. Should you be interested in booking at Vila, please download this form and send it to the specified address in the form.
Hotels and other options
You may also book rooms in the center of Barcelona. However, do not forget that you may not encounter suitable (and cheap) rooms if you do not book early since Barcelona is a hot destination for tourists.
