My stay was in June 2014. I only briefly met Iaia, who was very accommodating of our earlier than ideal arrival time.
The apartment is clean and has a very nice kitchen. Everything needed to cook a good meal was present, minus of course the ingredients.
I had no difficulty finding the building even fresh off of a transatlantic flight. It is very near to the metro.
The abundance of good food in the neighborhood, including vegetarian/vegan options, was a pleasant surprise.
The apartment is a great place to stay in Madrid. I only wish I could have stayed longer.
