Ruty and dervys are amazing hosts - they helped us with our bags all the way up the stairs, had very helpful tips about what to do in our four days in Madrid and readily answered all our questions about heating, etc. this winter was cold, but the small heater made the apartment very comfortable. We really appreciated the tokens of hospitality - the two chocolates, the breakfast etc, very thoughtful. The apartment itself is in a safe and very central location. Great cafes and restaurants, museums and parks well within walking distance.
All in all. A great place to stay in Madrid!! Super friendly hosts!!!
