Pros: My trip was very last minute and Mambo Tango was one of the last 4 hostels that were affordable for my budget that has air conditioning (very important in the summer!!) The location was perfect as it was only a 3-minute walk from the Parallel metro station which has access to multiple metro lines including L3 that also connects to L9 which is the airport line so it took about an hour from the airport to do 2 train transfers. The room I got was in the floor 1, room 3, with 8-bunk beds for females. There were 2 showers and toilets in the room. The bunks had a curtain for privacy and a reading light and a mini shelf with one plug socket. We also had access to a locker (bring your own lock). Towels were 2€ for rent. They have water and coffee in the reception area and access to the kitchen if you wanna cook or use the fridge. The place was clean definitely. Most importantly I met 3 lovely girls in the same room as me and we all hung out the whole time. It was an amazing time!
Con: the only issue I had was my bunk was on the top and it could get a little bit noisy climbing up the stairs to the bunk and it was a little squeaky so the person sleeping at the bottom might get disturbed.
