Oh wow, where to start...!?
From the first contact, we had fast and clear communication with the hosts (Andreas and Britte), who provided us extensive instructions both before and at the arrival.
Short before the arrival, we needed to prolong our stay in Madrid by 2 days - and it was no problem. The hosts were too polite to say that - but we suspected that they sacrificed their own plans to accommodate our request.

Now, to the apartment.
It is located in a residential area next to a large communication hub (Avenida America) and a few blocks from a 24/7 open convenience store ("Carrefour"). It's on the 3rd (and highest) floor and overviewing two courtyards - with limited insight from the neighbors. It's light, well-equipped, newly renovated and impeccably clean!
We loved it's design; a mixture of modern and functional domestic appliances and furniture and a retro touch - raw concrete beams, steel furniture, rough tree and cool lamps in different shapes!
The hosts have great taste for details. Just look at the painting in the living room, where the colors blend in with the sofa, the lamp-cord, the ceiling mobile and the awning. Awsome!
To conclude; our family of four (3 adults and 1 teenager) experienced our stay at Andreas and Brittes place to be just perfect - and it will be our 1st hand choice the next time we are visiting Madrid! But we guess that - given the location, the high standard of the apartment and the high level of service provided by Andreas and Britte, they will soon become "Airbnb Superhosts" - and the price will be much higher! :-)
Thanks, Andreas and Britte, for letting us stay in your lovely apartment - and our warmest recommendations to anyone who is looking for a clean, central and trouble-free stay in Madrid.
