I totally recommend this flat! Pizzi was really nice and helpful, giving me great suggestions on the city tour, nice restaurants and even helped me to find a place for covid testing during the weekend. The flat is really clean and has all the things you need. It is close to the Plaza Espana so has many restaurants around and close to many tourist sites. The street is a bit noisy at night because of the bars, but your bedroom is not on the street side so it's not a big deal for sleeping.
