We really enjoyed.
Apartment on the 3rd floor with elevator. The elevator is small but it did not bother us. The apartment is clean, quiet. There is heating, it helped us a lot since there were cold days. It is very pleasant to come from the street and the apartment is warm. The kitchen (it is small) has everything you need for cooking. There is a fridge, a washing machine and a dishwasher - everything works and everything is in good condition. All questions were answered immediately, and the hosts were so kind that they allowed me to leave things after 11 o'clock, when I had to get an apartment, that it was very convenient to walk around Paris without suitcases and then go to the airport.
The location of the apartment is excellent - the center, safe and close to all attractions. To the Louvre on foot, we walked about 20 minutes. In general, we highly recommend. Special thanks to Nicholas who was in touch with us all 5 days and was very kind.
