I stayed two nights at Carme's place. The flat is in a quiet residential area which is very accessible from the centre. She is a very lovely, warm hearted and welcoming host and does her most to accommodate. I didn't spend much time in the flat as I had a lot of catching up to do with friends but she was great all throughout. She can give you great guidance on Barcelona too, should you need it. I enjoyed my stay there a lot and would recommend her to anyone without hesitation. A truly great place to stay, with a great ambience with a great person for a host.
