Absolutely fantastic apartment in an ideal location. Israel made everything very easy, sending really clear instructions (including a video) of how to get into the apartment and find the keys on arrival. The apartment was spotlessly clean, bright, modern and comfortable. It is right by Puerta del Sol, so really central, with a huge selection of bars and restaurants nearby and easy access to the metro and train station. Israel answered any questions immediately and was very helpful. We really couldn't have chosen a better place to stay and we hope to stay there again some time.
