Carlos was fantastic from the beginning. He communicated promptly, provided the best checkin communication we have received from a host, and when we did encounter a minor problem he worked to fix it instantly.
The penthouse was exactly as the pictures show, and even more spacious. We had plenty of room and enjoyed the comfortable accommodations. The only regret we have is we did not leave enough time in our schedule to enjoy the amazing terrace.
I highly recommend staying here if your are visiting Madrid.
