We had a wonderful stay in Áureo's apartment in Madrid. The apartment was clean and nicely decorated and had all the amenities we needed. Muffins and fruit were provided for breakfast, and there were coffee, tea, and basic cooking ingredients in the kitchen. Having access to a washing machine inside the apartment was very convenient as it allowed us to pack lighter. We were able to control the temperature using space heaters (an AC unit was present, but we didn't need it as it was cold during our stay.) The apartment was quiet with very little noise from the street or neighbors. Overall it was a very comfortable stay, and we felt safe in the surrounding neighborhood.
The location was also very convenient. We walked almost everywhere; the Plaza Mayor is about 15 minutes away walking. Otherwise, two Metro stations nearby (La Latina and Puerta de Toledo) allowed us access to everywhere we wanted to go. Additionally, Áureo was very responsive and easy to get in touch with. I definitely recommend Áureo's apartment and would happily stay there again during a future visit to Madrid.
