The apartment is very well located, close to Sagrada Familia, in a very nice and calm neighbourhood. Roberto allowed me to leave my bags earlier on arrival and gave me a lot of information about transport, supermarkets (including organic store), restaurants, etc.
Although the stay was good, there were some aspects that could have been more taken care of. The cleanliness of the space could be better, namely inside the kitchen cabinets, the dishware and in the the master bedroom wardrobe.
The apartment is older and more worn than the photo appears and it seems to me that the price is a little inflated for the conditions of the apartment.
But, undoubtedly, the location and calm are the best arguments of this apartment.
