This flat/apartment was perfect for our family of 4. It was very, very clean. We loved having 2 bathrooms! It was so close to the metro and not very far from Atocha, Retiro, Puerta del Sol and other key places. There is a great restaurant and coffee shop just a few steps away. The air condition worked great, as did the showers. The instructions for accessing the apartment, and for leaving it, were clear and simple. I would definitely rent here again.
