Mario made our stay in Madrid very easy and stress free. We collected the keys from the airport immediately when our flight arrived. When we arrived at the apartment we were delighted with the cleanliness of the place and also the very modern stylish decor. Mario has made the apartment a joy to spend time in with lots of lovely art and furnishings. It feels like home. The apartment is very clean and tidy. I would highly recommend anyone who wishes to stay in Madrid to stay here. Great location!
