We recently stayed at this place during our visit to Paris. It is very close ( 5 mins walk) to Chateau Rouge station. Few points to note.
I would not recommend this area to first time visitors. We were 3 ladies and we did not feel particularly safe. We have travelled extensively around the world and are always street wise and keep our wits about us. But we felt very very uncomfortable around this area.
The streets surrounding Rue de Myra where the apartment is located, are rife with dodgy looking men lurking and watching you. It's not until you walk further uphill and emerge into Montmatre, that the area has a completely different vibe.
People step on each other, jostle each other, insult each other, spit everywhere, men and women.
If you are not buying drugs or hanging around flashing your wealth after midnight, there is nothing to worry about.
Because we were there for a short period of time we decided not to move elsewhere, as we would have wasted our precious time in Paris. So we decided we would use Uber/Bolt taxis once we stepped out of the main door to the apartment, and made sure our driver at night would wait till we got in the main door.
1.The apartment itself was nice and clean with basic facilities. Josias the host was really nice and flexible with the check-in and check-out.  2.The radiator in the bedroom was not working, which meant we were very cold at night.  3.The lock in the bathroom needs to be changed. It took me 20 mins to unlock the door, and almost had a panic attack as the bathroom is very small.
4.The coffee machine does not work so no point telling guests they can use it.
5.There was a power cut in the apartment, which meant we were sat in the dark for a good hour. As a result we ended up wasting time. Luckily the power came back after an hour but the wifi got unconnected. We rebooted the router but the wifi still was not connected. The power cut was beyond anyone’s control, but I am just thankful I wasn’t locked in the bathroom at that moment.
All this did not stop us having an amazing time in Paris, we just kept our wits about us all the time and used taxis instead of walking to get in and out of the area.
As they say location is very important when you have limited time, and the description on air bnb was misleading.
