The place is located at a very convenient spot with just 5 mins walk to the metro station on the main line, 10 mins walk to airport bus stop.
The neighborhood is quiet and safe, didn't feel anxious when I walked back from the public transportation alone. There are supermarkets around and many options for food on the main street.
The room is clean and it actually looks better than in the picture!
James and his wife are super nice, although I don't speak any of their languages, I can feel their kindliness throughout the stay.
I would recommend their place to people who are travelling to Barcelona:)
