Exceptionally clean (I mean seriously, though) and extremely comfortable (that bed...so comfy). They were happy to welcome me and my 16mo daughter, and the apartment was the perfect fit for us. We couldn’t have been more pleased with our stay. I would stay here again in a heartbeat.
I will say that the noise from the plaza is only audible from the front room. You cannot hear a single peep from the bedroom. But, Malasaña is known for its night life. So if you stay here, be aware. A fabulous value for Madrid!
