The apartment is on the ground floor of an apartment block near Chueca and the Gran Via. I was met by a friend of Pedro and Marina but I didn't meet the owners. The apartment was as advertised and is very clean. There is some noise at night due to the fact that it is situated in the centre of Madrid. You have to expect this. There was also not much natural light in the apartment. I think this is because the buildings are built to limit the sun and the heat inside. There are plenty of restaurants and bars in the area. Overall this apartment is good, secure( there is quite good security) and well managed.
