Staying at Chantal's appartment was a good experience!
First of all, the position is amazing: Located right at the Rue de Rivoli, everything was located in walking distance (e.g. Musee du Louvre 15 minutes) and we scarcely used the metro, although the station would also have been very near the appartment (4 minutes).
Something rather negative was, that it was really cold, although the heater worked properly. (Especially in the bathroom where there was no heater at all) But I guess this is not Chantal's fault but winter is just not the best time to visit Paris and I guess that Parisian appartments are just equipped this way!
The kitchen is equipped modestly but there are enough tools to cook a small easy dish. The bed is big enough for two people to sleep in. (The appartment looks exactly like the photos!)
The communication and the key handover went really well Chantal was very accommodating!
All in all, I'd recommend Chantal's appartment! :)
