Anna is a really friendly host and helped me a lot in my first 3 weeks in Barcelona. Her little daughter is really sweet and playful. In the flat there is a quiet and familiar atmosphere. In your bedroom and living room you have a great view over the whole city and even the sea, since it is in the 14th floor. The location was great for me, because my university was only 10min by foot from there and with the metro I was in city centre in about 20min. I can only recommend staying in Anna's apartment.
