I agree on the fact that the apartment is nicer than what it seems on the pictures. Spacious, well equipped and very comfortable, it is perfectly located to get to main places by metro, bus or even on foot (15 min walk to La Pedrera).
We travelled with young kids and my mum and we were the 5 of us at ease during our stay. The 2nd toilet is highly appreciated when 5 people! Good bedding and nice decoration.
Pere has been an excellent host, even without asking he sent us all the indications related to how to get to the apartment. He let us a map and a lot of useful information about Barcelona. Besides, we found some welcoming details and enough food for a 1st breakfast.
Very good experience, I strongly recommend!
