David and Merce's flat is very clean, modern, spacious, cosy and centrally located. Sants is a great area if you want to be in a more local atmosphere, with great bars and restaurants around and easy metro ride from the main attractions in the city. The room was really quiet (which is very important for me) as it overlooks an inner square and one can really have their privacy. David and Merce are just lovely, they made me feel like at home from the very beginning and they went out of their way to help me in any way they could - I could use the kitchen, the washing machine and the office room for working as I was staying longer, David recommended me a library very close by, he even woke up at 7 in the morning to help me with my heavy suitcase when I was leaving! I would definitely stay at their place again when I come back to Barcelona. Thank you for everything!
