We had a very comfortable one-month stay and overall enjoyed it very much.
In summary, if you are not dependent on on work video calls (I.e. anything faster than 1 mbps upstream), if you don’t mind minor annoyances like loose doorknobs and no ironing board, and if you have no needs that require a response from the management company, then the place is perfect.
In fact, the apartment really is lovely — wonderful neighborhood filled with restaurants, bakeries, cafes, and easy access to shopping and supermarkets — and it’s located on a relatively quiet side street just two block from Beaumarchais, located right smack in the middle between Republique and Bastille.
Jacques, the proprietor, is a very nice gentleman whom we met by coincidence towards the end of our 1-month stay. Jérôme, the property manager from the agency is also quite nice, but was probably very busy.
