Generator Madrid is an awesome super centric hostal to stay at. It was much better than what I had anticipated. I had all the amenities needed for sleeping, eating, working and having fun. The personnel was attentive and always helpful, ready to help me whenever needed. I met some amazing people during my 5 nights stay, and pretty sure created some long-lasting friendships.
I recommend this hostal in Madrid and I hope to visit their other facilities in the near future :)
