Sandra and Maria were amazing hosts. Very professional, and promptly answered all of our questions. Their professionalism and communication are unmatched. The apartment and the building were very clean and modern. Everything was exactly as advertised on the website. The building is centrally located and within short walking distance of many stores, supermarkets, bars, restaurants and major attractions. For example, it is just a short walk to Plaza Mayor, Royal Palace, Prado Museum, etc. We absolutely enjoyed our stay and will definitely stay there again the next time we visit Madrid. Again, many thanks to Sandra, Maria and the rest of the Gdiez crew for making us feel right at home in Madrid.
