Same feeling here: we also felt disappointed with having you.
What's wrong with staying in a guest room with paying guests? You didn't pay for it, It was free, as you expected. Volunteers room is for 4, if we didn't have an extra bed, we gave you an upgrade...
And you know that we had a problem with the lock, that's why you did not get a key. All girls in the room knew it.
It's also very unprofessional that you never said before coming that you couldn't work at reception, and then anytime we asked for your help at the restaurant (once it was the only thing you could do) you didn't care.
This is volunteer, not vacations. If you want vacations, you've to pay for it.
I didn't give you a bad review so as not to harm your profile, but as you can imagine I wouldn't give you more than one star either.
Wish you all the best for your future.
