It was okay, decent but that was exatly what we vere looking for! just a calm place to stay after our long travel days and nights so we were more than satisfied.
The quarter where the house is located is part of the modern Madrid so it's like round 45 minut walk from the Madrid busy center, or much much more faster with metro (wich is just marvelously perfect at Madrid!!! totally worth a ride!) would be round 10 minutes or even less i think.
