I had a great stay at Ricards place. He made me feel very welcome and was very helpful with anything i needed.
The apartment is in a great location in a neibourhood that has a very local feel to it. Just a short walk to the subway and your on your way to the touristy parts of town.
I would recommend this place to anyone and would definitely stay again.
Insider tip, If you want a decent coffee go to Onna cafe. Its on calle Santa Teresa which is on the way to the Diagonal subway station. As good a coffee as you would get anywhere in the world and they do a flatwhite as well.
