Esteban was comprehensive about my late check-in. The hostel is amazing. No shared rooms and bathrooms. A well equipped shared kitchen. Very well located. Nearby is the underground station and close to the Gran Via. Lots of facilities nearby. The bus station connecting to the airport isn't so far.
I stayed there for working. The internet connection is really good. I was able to run meetings without issues.
I’ll probably come back to Madrid, as a tourist, and certainly, I’ll stay here again.
