Gaspard is a lovely and kind host. When I arrived he was waiting outside with a smile. I was feeling rather ill and he allowed me to rest in his office before letting me up to my room two hours early, as soon as it was cleaned and ready.
Really appreciated the hospitality: he had a portable wifi device that we could use throughout our stay, which was a godsend. He was quite accessible by text the entire time, day and evening, for any questions. He also shared with us quite a few recommendations for eats and drinks in the neighborhood.
The apartment was clean and well-situated; super hip location close to cafes, restaurants, metro (expect a commensurate amount of noise around certain hours; not too bad though—pretty normal for Paris, and only in brief spurts when the city dies down and starts back up).
Lovely bathroom and I was impressed with the quality of the bed and pillows.
