Alvaro is a superb host who cares a lot about making your stay as comfortable and enjoyable as possible. He strives to be an excellent host and in doing so is very fun to be around, super informative about everything and helpful in any situation. If he is available he will spend time with you and show you the city which is a nice treat. Also his communication is amazing and he checks in and let's you know all you need to know before you even leave to Madrid. I'd have no hesitation in staying again. His house is in a very handy location right outside a metro station and quite central. A supermarket right across the street also is handy. The bed is comfy and you have all you need for travel. He cleared space in the fridge for me and even offered to do my laundry. Highly recommended.
