It was our first visit to Madrid and we spent excellent time thanks to Andrew! It was a great experience to live in the center next to all major sights. We didn't use any public transport(only once to get to the apartment) and all the rest time just walk exploring the city. The apartment is really very nice and fully equipped with everything you need. The 7th floor is not a problem, there are only pluses: the apartment is quiet, sunny and has a lovely view, also free sport included :)
