I stayed at Marcos’ place for a month and it was great ! His place was very clean when I arrived and the location was very central without being noisy since it’s on the top floor . The apartment is compact but has everything you need and the bed is very comfortable (something rare when you stay at different airbnbs). The flat is right behind the plaza mayor and a five minute walking distance to the opera , sol and la Latina . It was so easy to communicate with Marcos and he would regularly check up on me to see how my stay was doing and was always available if I needed any help. I highly recommend Marcos place to anyone who’s would like to enjoy Madrid and to feel safe during their stay ;)
