Four friends.
Rules flat was spacious, comfortable, well-appointed, very central and well served by public transports. Two large double bedrooms, both served by their own WC/bathroom, separated by a large lounge and the kitchen. Conditioned air. TV. Internet WiFi. Quiet building with elevator. Ideal choice for visiting Madrid on foot with friends, but also for couples or families. Raul was very kind, courteous at our arrival and very timely. Always available, but discreet. He's so nice, serious and reliable. I really recommend this place and this host.
