Instead of Carmen we met Silvia, who is a very kind person. But keep in mind, she doesn't speak any languages other Spanish. She even let us to leave our luggages on our last day in the apartment. The location is very good, near to the underground, to many sights as well. On the corner there is a small bakery, the place is amazing. The flat looks the same as in the photos. But the shower is extreme small.
Only problem for us were the very thin walls. And there were no words about tax, what we had to pay, when we arrived.
The flat is to recommend.
