Great little place and a perfect base to explore and "get lost" in the old city. I didn't get to meet Quentin, but he was an excellent communicator and was always available to answer any question and very patiently helped me with a very early morning airport transfer.
The apartment is newly renovated and very charming, with a great use of a small space. I loved it! :-)
Just a note about the noise from neighbours - it can, at times, sound almost like they've entered into the apartment. It can be a little annoying, depending on how affected you are by noise...
Other than that, this place is thoroughly recommended!
