Stayed in Mambo Tango for five nights and thorougly enjoyed the time there. The staff were extra kind and always helped with any questions I had. The dormitory room, kitchen, bathrooms and hang-out spaces were tidy and in excellent condition. Breakfast was fairly simple (toast, cereal, fruits, coffee and tea) but free of charge. Also the location of the hotel is very good as there are many options of public transport nearby. In the vicinity was also the Montjüic mountain, which was a nice 1,5h hike up and down to see the Fortress. Thanks MT, would come back in a heartbeat!
