Highly recommended 10/10
Christian is very professional and comfortable to be around. The best stay and yet so affordable, not so far from the centre. Many amenities can be found nearby such as ALDI, KFC, a park, and the metro/ bus - all within 3-5 mins walk. Cleanliness 10/10, communication 10/10, accommodating 10/10. If you are travelling to Madrid definitely consider staying here, you will not be disappointed.
