Location, location, location! This apartment is located in such a lovely, lively, and authentic area. You will feel like a local. The apartment is very close to the heart of Paris and is walkable to many areas of attraction. We walked to most places within 15-20 minutes, but could have easily used the metro to get around (didn't because of the country-wide strikes).
From the moment I booked this place from the host, communication was always quick and clear. The host uses a concierge service who is very helpful, including an option to provide shuttle service to and from the airport. We utilized this service without any issues. Getting access to the Airbnb was also very easy.
The place itself was very clean, stylish, and comfortable. There are 4 bedrooms with each room containing a queen sized mattress. There were plenty of towels and pillows (check the closet on the main floor for extra), but my suggestion would be to bring your own pillow if you have room in your suitcase as every pillow there were very thick/tall -- but maybe that's a personal preference.
There are 2 toilets and 3 showers. I'll break it down for you: one full bathroom (including toilet, shower, and sink), one watercloset with a toilet only, one bathroom with a bathtub/shower combo and a sink (no toilet), and finally a shower and sink attached to a bedroom upstairs (no toilet). Do note this apartment is located on two levels, with the access to the second level only by stairs. Upstairs, you will find two bedrooms, including the bedroom with the shower/sink combo.
WiFi is available in this Airbnb, but it's not great. We experienced connectivity issues, but when it worked, it worked OK.
Overall, there was plenty of space for our group of 6. I would 100% stay here again as it was such a great experience. This place is wonderful and I encourage you to book it.
