We passed a family weekend in Gunnars apartement and had a really great stay, 6 adults different ages and one 3 year old child.
The apartement is fantastic, just as described. Perfect location for discovering Barcelona on foot. Nice cafe below on the street offering breakfast, convinient store in front. The place was clean and organised, heating and showers running well. TV and wifi for relaxing after a long day in the city. Nice area to go out at night for dinner.
Big thanks to Gunnar for exellent communication before and during our stay. He helped us organize airport transfer for the group, and quickly responded to any question we had during our stay. We arrived around midnight and were handed the keys by Gunnars relative.
To summarize, we would absolutely come back :)
