Fantastic apartment and lovely host! Luz immediately made us feel welcome when we arrived in the flat. I had mentioned in passing that it was my boyfriends birthday and she had a birthday card and decorations in the flat to greet us. It's in a great location, easily accessible from the airport on the renfe and within walking distance of all the sights of Madrid. The apartment is stocked with toiletries and breakfast essentials. Mercado San Miguel is across the road for delicious Spanish food, and there is a food shop close by.
We would definitely recommend Luz's apartment and if we're in Madrid again we'll be looking to stay here!
