Rosy's place in the Latin Quarter, the 5th arrondissement, was perfect for our needs. Right next to Metro lines 7 and 10, we were able to get around Paris with ease. There are local cafes, late night restaurants, markets, bars, and the apartment is close to the Pantheon, Jardin des Plantes, the Sorbonne, St. Germain de Pres, the Seine.
My daughter loved the 88-key keyboard. The office was a huge bonus room. Plenty of sunlight and windows and a nice cool breeze. The building was safe on a beautiful, quiet side street, yet steps away from all the lively happenings around Paris. The bed was amazingly comfortable, the kitchen had all the amenities one could want, and the view of the Paris rooftops was very pleasant.
We highly recommend Rosy's place.
