First, the positives. It is a charming, old building in a true Parisian neighborhood. It was clean, and had a small elevator for luggage. And the service provided by Aldric, the property manager, was truly professional and caring. Aldric was the best! However, the description is not accurate, and we never would have booked this had there been an accurate description, as it did not meet our needs.
First, as another reviewer noted, there is NOT wi fi service. (I did not see that review until after we arrived!). The owner uses wifi from another apartment -but it is an old brick building, and so it doesn't work. The "solution" was to work in the lobby - but there is no motion sensor to keep the light on, so I had to work at midnight alone in a pitch black area, standing up, while hearing noises from the next room where the trash is kept. Very creepy. And, unfortunately, wifi didn't work there either. So I ended up paying a ton of money to use my own hotspot.
Second, there is not 1.5 baths. There is a toilet in a utility closet (next to the mop bucket and under the hot water heater). Down the hall in the laundry room is a sink and shower. But the door to that room is glass, and the shower enclosure is glass, so if you're walking down the hall while someone is in the shower, you have no choice but to see them!!!
Lastly, there is not a master suite. There is a large bedroom, but no adjoining bath. As noted, one toilet in a closet. If only my husband and I were traveling, and if I did not need wifi to work, the apartment would have been a fun and charming stay. We have stayed in Paris before using Air BNB, and know that the city has tons of fun quirky buildings, and you have to go with the flow, but an accurate description would have kept us from booking this.
