I had such a good time at Carolina's, she's so friendly and welcoming, I enjoyed talking to her, she's really really great! The room with the private bathroom and toilets are perfect for a lone traveler and I enjoyed this privacy. The flat is very well located, and I was able to visit a lot of places without getting lost in Barcelona (and without GPS ^^ ). Carolina is such a great person, she's so kind and she even called a taxi for me the day of my departure when I had a change of program (quite unexpected). I highly recommend this place if you are to visit Barcelona alone, everything's perfect!
