Elsa's apartment is located in a nice residential neighborhood of Madrid. There is a metro station two minutes from the apartment as well as cafes, restaurants, a local food market and supermarkets. Just few minutes down the road you can also find an award winning Paella restaurant!
Communication worked Ok and although we didn't meet Elsa, a housekeeping lady kindly let us leave our luggage in the apartment to allow us start sightseeing Madrid early, as we had had a relatively early flight.
Some tips and information of the immediate area would have been a nice thing to have (Welcome pack).
