Alfonso is a wonderful host. His communication is top notched and he'll help you with suggestions to visit some places. He's a great cook and even made diner for me.
The room is clean and nice as described. When it's hot you can use the ventilator on the ceiling. The bathroom is nice too.
The location is good. From the airport 15-20min to Placa de Espagna and 5-8min walk to his place. If you like to walk, the Rambla is a 20-25min walk or easy to take the public transport.
