We had an incredible time staying at Sergio's apartment in Madrid. The apartment itself has a wonderful layout and the rooftop deck is breathtaking - we enjoyed having wine and conversation outside. The apartment is in a great location - the Renfe train station is directly across the street, which was convenient when it was time for us to head to Seville. It is also within walking distance to the "center" of town and the botanical garden, but right on the edge of the madness, so you have more of a local vibe when you step outside. The living space is very comfortable and large. We truly enjoyed our time here and would return and recommend it to anyone coming to see Madrid.
