Loved staying in Desagnat's place. They were super helpful for our check in and checkout, accommodating our requests. The location is fantastic - you can walk to the Louvre, Notre Dame, Musee D'orsay and many many more places. The latin quarter at the doorstep is very helpful too.
The flat is clean, very spacious and very well decorated. The features such as the piano converted into the kitchen cabinet made for interesting discoveries every day.
All in all, a lovely stay. Would happily stay again.
NB The steps to the flat did not bother us, but may be something to consider for others.
