We had a great time in Madrid. The apartment is very centrally located - imagine being just off Leicester Square. This means you have great access, within walking distance, to all the sights of the city with Metro station within 50 paces. However it also means you have the sounds of the city, too. This made sleeping in the front room difficult, even on a weekday night. Would recommend bringing ear plugs if you plan to sleep in the twin bedded room or on the sofa in the lounge. Otherwise everything else with the apartment is great.
