Positive - fantastic location, just 2 min walk from St paul's metro. Also great from restaurants & grocery downstairs. 15min walk to Notre dam. Has most amenities needed in the apartment. Only 2 flight of stairs which is good in Paris. Large & newly renovated bathroom. Getting to apartment was smooth & manager was waiting for us there. Checkout is smooth & self service.
Negative - The owners live in US and there is an apartment manager in Paris who does not understand a word of English. She just pointed at different things in apartment, even when we asked a question about equipments, she started explaining in french. If that is case, one should have basic instructions about equipment in English. We could not operate microwave for 4 days we stayed. The internet was a hidden network & again she was not aware of it. The network name was typed wrong, so it took some effort to get internet on our phones. The fridge works but door is really hard to close & you fear that fridge may come out if you press too hard. The dryer ran but did not dry the clothes despite different settings. I wanted to inform the owner but by that time the communication channel with him already broke. This is what happened - they gave 3 toilet rolls for 4 people for 4 nights stay, 1/2 used paper towel, 1 washing machine tablet, 1 hand soap in bathroom. When I asked if we can get more supplies, the 1st response was this is an Airbnb and not a hotel. I find it hard to believe that for the price we paid, were we asking for too much? The owner said that 3 toilet rolls is what he will provide. He kept on insisting that there were more washing machine tablets in the apartment but we could only find more detergent tablets (dishwasher ones). I wrote to apartment manager also, but she never replied. Finally, after some back & forth, the owner said that if we are not happy, we can find another place & he will refund for remaining nights. You cannot find a place a Paris at last moment, and this was an unnecessary show of power play. Anyways, we bought the supplies needed. We could not find garbage bags as well, which we found later once owner pointed us to right place.
There are days when things are not going your way, may be this was one such a trip for us. Never had similar issues in any other Airbnb (I am sure owner will say the same for us). Hopefully others have much better experience at this place
