I bet Angel is the best host in Barcelona. He's very responsive and kind. Also, there's paper where he listed good restaurants, wine shops, bars. And if you don't know where to go and don't want to search google, it'll be your mini michelin guide.
Also there are lots of art pieces. You can see how Angel loves art and know what beauty is. Most importantly, its location is perfect! Close to everywhere!! We loved Angel's apartment and his place made our trip fabulous!
