The studios (there are three on the same floor) are ideally located as Anne states on the title of her listing! They are right in the centre of Old Nice on the 'place du Jesus' which is a small quiet square with only one restaurant that doesn't stay open late and has no music. Some parts of Old Nice can be very noisy. You are 5 minutes walk from the Promenade des Anglais, the beach, and also the place Garibaldi where the buses leave for Monaco, and all the other places to visit in the region. The buses are very cheap, 1€50 to go anywhere.
The studio is incredibly well equipped and comfortable for a summer rental (and I am a seasoned-traveler!) Anne has really made an effort to make sure her guests are happy, she meets you at the tram stop, and she provides a brilliant Guide that includes information for getting around the area, shops, bars, etc. The wi-fi in the studio worked perfectly.
This will be my destination for any future trips to Nice without any hesitation.
