It would be hard to find a better location that Juan's apartment in Barcelona. It was an easy walk to the beach, the park, a wide choice of cafes & restaurants, and to Metro stops.
We parked on the street a few blocks from Juan's. I was a bit concerned about leaving the car there for several nights but my fears proved unfounded. In fact, there are several secure parking facilities in the neighbourhood, had we chosen to use them.
Juan himself was the perfect host. He gave us lots of time as soon as we arrived, helped us find a parking space, gave us a thorough tour of his flat and how to use things like the shower and fan, spent ages talking us through a map of the city, and gave us all sorts of useful advice. He also helped me book tickets online.
Juan rents out 2 bedrooms via Airbnb, so there were other people staying both nights we were there. Usually this didn't create a problem with accessing the bathroom since we were all coming and going at different times. We spent a very relaxed 2 days in his home and found him an easy-going and generous host.
The day we were due to leave, my partner was rushed into hospital. I text Juan to let him know I'd be late picking up our cases. He immediately replied, asking if I had somewhere to stay that night. He made all the arrangements for me to stay at the apartment of his friend Miquel, just by the Park Cuitadella, and they came to pick me & my luggage up in the car. (Miquel is also an Airbnb host - his apartment is fabulous and so is he.) Juan offered to accompany me on my hospital visits & told me to phone him at any time if I had a problem. His extreme kindness turned what could have been a nightmare into a surprisingly pleasant unscheduled extra 2 days. One on a million. Utterly recommended.
