Sonia's place was nice and definitely big enough for four people. She left us coupons for sites around Barcelona, a bottle of wine, a bag of chips, and a bar of chocolate. They are definitely welcomed after a long day of traveling. It is close to the metro and several bus stops so easy access to the city. It's also at the top of a hill so plan your footwear accordingly. There are several restaurants and bars around the apartment, and there was surprisingly a concert just a few blocks down. Very lively neighborhood, super safe and convenient.
