The flat is extremely well located, no need for public transports you can go to all the touristic places by foot, the flat is very close to the museums, parque retiro, train station, city center, markets etc.
The flat was clean and just like in the photos. The best is obviously the rooftop, perfect for resting during the hottest hours of the day and for nice meals. I would definitely recommand it to anyone planning a trip to Madrid.
We had a late flight out of Madrid but Susana found a way for us to leave the luggage anyway which was greatly appreciated!
