My sister and her family were the ones who stayed--here is their review:

"Our stay at _______ was extremely pleasant and extraordinarily convenient. The apartment itself was clean, well appointed and easily accessible. Rosa and Nicolas had provided plenty of useful reference materials for Barcelona and its environs and the walk to the old port or La Rambla was a reasonable length and the neighborhoods were both scenic and comfortable to navigate at any hour. A trip further afield to Sagrada Familia was made all the more convenient by the proximity of the metro station (literally steps from the apartment building) and taxi service is easy to hail from the street near the metro station if desired.

And if the apartment amenities and proximity to attractions in Barcelona were not enough, Rosa and Nicolas were remarkably welcoming and generous with their time in getting us oriented to the space of the apartment, the offerings of the immediate neighborhood, the details of transport and suggestions for activities and places to eat. Indeed, in a meat-focused culinary environment, Rosa and Nicolas were quick with suggestions for our vegetarian, and their local tapas suggestion was spot on. We cannot say enough positive things about our hosts’ (and they really were hosts) willingness to spend about an hour plus getting us oriented and then making themselves available via email with prompt responses to additional questions that came up over the three days we were there. We could not have asked for a better experience in Barcelona!"
