The attic room is clean and big enough for two. The bathroom is quite small - but the big terrace is compesation enough - what would you rather like - big bathroom or a big sunny terrace? and you can see the Sagrada right from your breakfast table. The location is a way from the touristic hot points but there are two metro stations within 5 and 10 min walking distance. To the Sagrada it's about 10-15 min by foot.
There are several supermarkets nearby, two bakeries (one is open on sunday as well), and several coffees/pubs (we weren't in them, so we can't say anything about them).
We had a great stay despite the treacherouse weather change on our third day - which was why we really appreachiated the hairdryer to dry our soaked clothes and the fan heater :)
