Communication with Gemma was really easy, she answered always really fast to all of my emails and left us a welcome drink for Christmas, thank you! She was a very nice host.
Unfortunately when I arrived, I realised everything was managed by an agency and because of that I had to pay 20 euros more, because of the tourist tax in catalunya. I had a very unpleasant talk with the guy from the agency, who actually told me it was not a lot of money so I shouldn't be complaining and also gave me a tax lesson... but strangely I never received an invoice for the money payed. Apart from that I had to sign a contract with this agency... I think all of the charm and lay back service of airbnb acutally faded away...
Anyway, the apartment is very well located and beds are comfortable. The bathroom was clean and big :) It is true it is loud, although the new windows are really good... the problem is when you open them.
We had some problems with the washing machine, but we figured it out. All in all, it was really good, pictures are accurately. except for the incident mentioned above and.. oh yeah if you want to pay by credit card the they charge you 2% more... I would have appreciated being informed! Enjoy BCN, it is an amazing city!
