I did not had a good experience with Surfgasm.
First they accepted my stay, but they didn't give me all the information. When I arrived in the hostel, the person that accepted my request wasn't working there anymore. Nobody knew about me, then one volunteer called to the manager and she said to me send me curriculum by email. I said yese but I told her that was something wrong because I had applied as a volunteer. After that I applied to another hostel and my experience was amazing.
I don't indicate Surfgasm.
