Myself and my wife stayed here when we went to Madrid to take part in the marathon. Ale is a great host and was always very prompt to reply to any queries I had. Our inbound flight to Madrid was delayed which meant we would arrive later than expected, he assured me that this was not a problem at all.
The accommodation is very clean and has all the essential amenities that you will need. Camilo the cat always comes to great you and say hello after a long day exploring the city. The room itself is the perfect size for two people and is very clean. The phone and device charger cables are a nice touch as you don't have to fumble around with adapters.
The location is great as you're only about an hour walk from the center of Madrid and all of the attractions, or if walking is not you're thing there are plenty of bus stops and metro stations near by, and what we also found was that an Uber was never more than three minutes away.
We would highly recommend staying here if you are planning a trip to Madrid!
Thanks Ale!
