Very nice location, in the real center and a famous avenue, but very quiet (the apartment is not on the street). A little tough to climb the 5 floors with the luggage but fortunately, it's only once (except if you really want to make a big lunch at home !). Rut and Oscar are very nice and helpful, they left some things for breakfast (sugar, coffee, milk, bananas and cakes..). We could leave our personal belongings when arriving, although it was earlier than the official time, and they let us stay longer in the apartment because the following guest arrived later. Everything is clean and modern in the apartment and we definitely will stay there again when we come back to Madrid ! Thanks !
