Fantastic apartment. Clean and comfortable. Spacious with a lots of light. Be aware that it is on the 5th floor so there are stairs to climb which is not unusual in Paris.
The location is excellent. Right around the corner Place de la Contrescarpe (one of my favorite spots in Paris) in the heart of the Latin Quarter. You can actually see into square from the balcony which has nice panoramic views. Tons of cafes, restaurants and bars around. But as soon as you close the windows, it is so quiet and peaceful.
Roya was an excellent host. Quick to respond to any questions and graciously allowing for a late checkout. I would highly recommend the apartment and will definitely look for it on my next trip to Paris.
