Brilliant location. We took the RERb to Les Halles and walked from there. The area is lovely, actually our favourite area of Paris having walked to pretty much every other arrondissement! Lovely cafes and restaurants/bars nearby as well as covered market (marche des enfants rouges).
There are quite a few flights of stairs to the property but that was entirely expected given the floor it's on. We had everything we needed there to cook dinners each evening (to save money and make use of the local produce). The bed was very comfortable and the street is quiet so sleep was never an issue.
Michael was really helpful and responsive, we never met him but knew that he'd get back really quickly if we needed anything.
Great stay, thanks again!
