I have had such a great time in this little bright studio. There is no elevator to the 5th floor, but you get used to that and the views over the rooftops are wonderful. Hervé was a nice and thoughtful host and everything you need was in the studio. Although we didn't meet in person, the communication went flawless and the instructions for check in were very clear.
The location near the Jardin du Luxembourg and the place de la Sorbonne is just perfect, next to the studio is a supermarket and there are a lot of things you can do on foot. I would definitely recommend Hervé's place.
