Montserrat welcomed us in time and she was very kind to us in giving some maps of the city which were very handy and some advices where to go - what to visit and where to eat, which was also great and helpful! So thanks to her for that!
The flat was a little bit further from the center than we expected but 3 different bus stations are near the flat so it wasn't a huge deal.
The room is actually better than at the photo (for our taste) so it is a little bit outdated, but we liked the room.
As for the downsides it was sometimes it is a little bit noisy in the flat and the were little space in the refrigerator. It all can be improved, but all in all we liked our stay, it is totally worthy for this cost.
