Corso 37 is in great location with Pantheon, Trevi fountain within 15min walking distance and of course Spanish steps which was 5 minutes away. One thing to be aware of being so central is that Via del Corso is a restricted street so depending on the time of day cabs would not drop you off at doorstep and you do have to walk out nearby taxi stands. Apartment has 2 nice sized bedrooms and flexibility of having 2 spare beds was great as we were traveling with 3 kids. Another plus was big stock of clean linens/towels. Good workout everytime going up to the apartment as is on 4th floor but on arrival caretaker greeted us and helped with all our suitcases to the top floor which was fantastic! Mauricio was very responsive to any queries by whatsapp which was also very helpful for our stay. Overall great stay!
