The apartment is done with style, and was extremely comfortable. Superbly located - close to 2/3 metro lines, cafes, short walk to main tourist attractions and even a laundromat is right across the apartment.
Christian was very quick to respond to our messages and queries. We thoroughly enjoyed the apartment and everything was very well done and super convenient. Having powerful air conditioning was a blessing in Madrid's hot hot weather.
Staying there gave us a posh luxury feeling, would stay again if we go back.
We would definitely recommend Christian's place to anyone visiting Madrid.
