Visiting Barcelona from 12th to 16th November 2015

Hello everyone!!!

I will be visiting Barcelona in the best festive way and would like to have some ideas for the best dancing, drinking and eating places.
If someone is available and would like to take me around also is very welcome to contact me :D
I will be staying at Barcelona Princess Hotel.
Does anyone knows how much might cost the transfer from the airport?
