Gelso is definitely a great flat to stay in when in Milan. Greta was very good at communicating and made every effort to accommodate our arrival time. The location is very good and you are close to some great dining options and the Metro (Red M1 line) which is 3 stops away from Duomo. The apartment is located on the 4th floor, however it felt more like the 5th based on the stairs. There is plenty of space and you will be very comfortable during your stay. Also, some of the floors are squeaky (may be an issue if you have a baby who is a light sleeper). Overall, we will look to stay here if we return to Milan. Thank You Greta!
