Not recommended. Despite hosts being a friendly couple, the apartment is in really bad shape and in great need of repair. Here is a list: the couch was so stained we couldn't use it; broken freezer door (had to be taped shut, but still leaked water into the refrigerator); bathroom sink is clogged, so it takes forever for even a little water to clear; broken handle on the washing machine; the only cooking pan is so flaky in its nonstick coating it would be toxic to cook with.
The most unpleasant thing, however, was the bed (or the mattress to be exact). The "clean" sheet and covers provided smelled so bad we had to wash them again. But I still got a rash and bumps on my back and neck. There might be mites or bugs in the mattress. Yucky! Had to buy a bed sheet ourselves and wear pants to add some additional barrier.
And oh the neighbor!!! Who couldn't stop his loud and continuous monologue every night, sometime until 4:00 in the morning. I used ear plugs but my poor boyfriend suffered. Nope, didn't rest well at all.
The apartment might have been nice a long time ago. But it's been so run down and neglected that our stay here ended up being one of the worst airbnb experiences we've had. I love Madrid and the Lavapiés neighborhood. It's a shame our final week in Madrid didn't turn out so well.
