Good apartment, really great location at 5 minutes walk from Opera Garnier. You can find everything you need for the kitchen (good tea, coffee) and the bathroom, supermarkets and lots of restaurants are right nearby. Also the communication with our hosts was perfect, they were very helpful!
Two minor things: the apartment is on the sixth floor without elevator (is in the description that it's on the last floor, so if you have problems climbing stairs take into consideration that there are six levels) and the cutlery was kind of sticky (maybe a problem with the detergent or smth). Otherwise, everything was nice and tidy.
