We really enjoyed staying at Marta and Paul's. They were always quick with their responses. Their friend Josef checked us in and he was timely and in constant communication. He also recommended a great tapas spot. The apartment was completely comfortable and bigger than we expected. The outdoor space is amazing! Bring your own toiletries (shampoo, body soap, etc.). We loved the neighborhood (not touristy), and you are right by a public square to just sit and people watch. Also their is a grocery around the corner, bodega across the street and walking to the metro/buses was easy.
