Location is perfect, you won’t get this elsewhere with this price.
Miguel’s mother hosted me, she was super sweet and we were able to communicate fine despite her not speaking English and myself minimal Spanish.
Shared bathroom was clean.
Commentary on the room itself (this is not criticism, rather this is to make sure you know what you are getting into):
The room is rather small, doesn’t have windows, and doesn’t have A/C. As such, it can get pretty hot. There is a fan installed to ameliorate some of this, but keep this in mind in the event you show up on a hot day or if you choose to stay here long term.
This works best for solo travelers on a budget hoping to be in an optimal location in Madrid for a short time. I walked everywhere (literally did not take the subway once).
