Malena was a really good host. I stayed at her place for two weeks for a work related trip. She greeted me upon my arrival and gave me the keys to the apartment, and was always available via whatsapp if I needed her assistance. The apartment is very clean, and looks just like the photos. It had all the amenities needed, and she even provided fresh towels and bedsheets. The neighbourhood is very central and a very short walk to Pacifico metro station which can easily connect you all over the city. Its a safe neighbourhood and its near the Retiro Park too which is beautiful! I definitely recommend staying at Malena's if you are in Madrid.
