If you want to avoid stress, waste of money and time, simply avoid Student.com.
I made a €200 deposit to book a room, but the landlord said that it is not available anymore and that they won't return my deposit. My student.com agent does not answer me anymore. For all I see, I must have been stolen.
I started talking with "Linda" from student.com after seeing a single studio accommodation in Barcelona. I was interested in booking it for 3 months. Linda seemed to be in a rush to make me book it, like she was more interested in achieving her sales goals than helping the customer. She avoided my specific questions about the accommodation and kept asking me to make the payment to book it.
She provided me with an email login and password for an external website and said that I should make the payment there. I wrongfully thought that Student.com was trustworthy and made the payment there for a single studio.
Now, the landlord has contacted me saying that my single studio is not available, and they will not return my deposit for months, IF they return.
I have tried contacting student.com and my agent, but nobody responds nothing.
So, from what I see, I was stolen €200.
While many people succeeded in booking using Student.com, watch out because maybe you'll be the unlucky one to be stolen.
