Nice cozy place with everything you need. Pilar is very sweet, she will meet you at the apartment and show you everything you need. She has very limited English, but uses the translation app to communicate. It worked fine. :)
The bed is comfy and everything is nice and clean. The neighborhood seems a little dodgy at first, but the apartment in in an enclosed alley and feels very safe. We just did not wander around at night much and everything was fine. The location is great for walking or taking public transportation to the sights of Madrid. There are two nice grocery stores right up the road in Tirso de Molina. I would avoid the Nelson Mandela square down the hill from the apartment. That is where it seemed troublemakers liked to hang out. The neighborhood is full of a great variety of ethnic food.
