I stayed two weeks in Paul and Marta’s flat. The flat is very nice - clean, modern, lots of natural light, and on a quiet street in Gracia (which makes it perfect for opening the terrace doors). It is also close to lots of bars, restaurants, and shops. Paul and Marta were responsive. My only issue was that I requested early check-in and wasn’t advised until several messages later that there would be a Euro 50 fee. I understand there may have been a cost to pay someone to meet me earlier, though the fee seems high and could have been disclosed in earlier correspondence. Other than that, my stay was quite lovely.
