We are a couple living in Barcelona for the last decade. My partner is Colombian and I am Belgian. We have an almost 2-years old son. I work as a psychologist in a school and my partner is self-employed. This gives us quite some free time to travel. We used to be backpackers, but with our son we need a bit more comfort. We've stayed before in other people's flat and house, booked through Airbnb, and we also rent our flat out.
