Helios' place is sensational. Right in the middle of everything, a short walk away from the Palace, Plaza Mayor, Museo del Prado, a multitude of parks, restaurants and nightclubs. The place was spotless when I arrived, and Helios was always very quick in answering any msgs sent by me, and even when I asked to leave my bags before checking in, he did everything in his power to help me. I only don't recommend it more because then I won't be able to rent it again once I'm back! 😁. In all seriousness, 5 out of 5
