Albert and his family (aunt and mother) are definitely super hosts. There was some trouble caused by a thunderstorm that damaged the elevator and the wifi. Since I was travelling with my grandmother in a wheelchair, Albert and the family took charge and rented a hotel room for a couple of nights to make my grandmother feel as much confortable as possible. Additionally, Cleotilde (mother), hung out with us for almost a whole day and showed us the city. Her aunt was very nice and helpful too. We are very thankful with all of them.
Regarding the apartment it is extremely well located, confortable for 4 people, well equipped, clean and the pictures are accurate.
Totally recommended when going to Barcelona.
