After spending a few days in Barcelona we can only conclude that choosing Rafael's and Tania's hosting offer was a great idea! :)
The apartment was clean and in excelent condition (exactly as a photos show).
The location is just perfect: close to metro, near shops and Tapas bar with local specialities. Tania is a lovely woman with a great sense of humor, she made us feel very welcome.
We enjoyed staying there and we definitely recommend it! I'm already sure that this will not be out last visit in Barcelona and if so, we will choose Tania's and Rafael's place to stay, again! ;)
