My friend and me we both stayed for one night at Flavia and Marios apartment (with private bathroom) and it was excellent! Flavia and Mario are amazing hosts, super friendly and caring. The apartment had a fully equipped kitchen with microwave and coffee machine, WIFI and towels - so everything you need is there! The communication was great - both replied always were quick. I can highly recommend this place to anyone who likes to live with locals in a very central apartment in Madrid. Thank you for everything!
