Response from Daniel:
Thank you Maria. I enjoyed staying at your home.
I might be looking for a couple more nights, 10 & 11 January 2013, so I'll have a look at your availability on the AirBnb site soon.
Oh, one more thing,I've only just realised I have your Barcelona Lonely Planet guide with me, so I'll make sure I get it back to when I'm there in January.
