The good: Great, bright, artsy designer flat in historic building with high ceiling. At the centre of Paris. Elevator and car park. Good communication and check in / check out.
Room for improvement: The bed is two small for two people, one of us had to sleep on the couch, way to go for a romantic stay in Paris. That is not acceptable as sleep is the primary concern and requirement for a place to stay. It is a shame as the flat is otherwise great. The wifi is slow (11Mb/s) and shuts down regularly, not allowing for online meetings, so not suitable for travelling professionals. I recommend upgrading the landline.
