We stayed six nights in Catherine‘s appartment - it was great. Clean, everything that you could need available (washing machine, fully epquipped kitchen etc.) and the location is great for a city trip. Very close to the Arc de Triomphe de l‘Etoile and therefore to the Champs-Élysées.
Also public transport is very close (subway & bus). We parked our car in a reserved parking spot located in the private underground car park of the building. The parking spot is quite large, a BMW 3-Series fits well, BMW 5-Series would be no problem as well.
Communication with Catherine was very nice, she responded fast and was always very help- and thoughtful! If we come back to Paris, we would absolutely consider to stay at Catherine‘s place again, if she would have us!
