I stayed for over 1 month. Luis is an amazing host. The communication with him was always very good. He even waited on me because my flight was delayed. The location is perfect, not far from the Ramblas; the street where the hostel is located has its charm. Local vendors everywhere. The room was as seen in the pictures with a private shower and toilet. Rare find for this price. It could be a bit noisy at the night from the surrounding, but that is Barcelona for you.
WIFI was very strong and fast, the communal kitchen was always clean. Every week I got clean linen. On the last day when I was leaving Luis came outside with me, just to make sure that I found a taxi to the airport. Overall experience: TOP. I fully recommend this place.
