The hotel itself and rooms are ok. We had a problem with our room on the first night, it was dirty (you could feel that it was dirty), itching after sleeping on bed, I don't think it's bed bugs but maybe dust mites. I am not sensitive to this and even I was feeling the itch. The shower was a bit clogged and water was taking a long time to drain out, this was absolutely disgusting and my wife almost had a breakdown. The closet had a female underwear in it (from the previous guest i assume). No AC in room which is not a problem, if only the streets didn't smell like urine, the windows could have been opened.
So we changed rooms and the second room was a bit more like the photos and description. It was much more comfortable. but maybe still itchy - or this was in our minds now.
The staff are super nice and accommodating.
After reading the reviews, I thought the neigbourhood was being exaggerated, but in reality, it is a bit rough, sketchy, and dirty (urine everywhere) and characters hanging around all the time. I didn't feel threatened just dirty as opposed to the other charming side of montmartre which i remember and am so fond of (where sacre coeur is). This is not that side.
fairly close to metro and sacre coeur but have to pass through a 5 minute garbage slum to get to it. WE absolutely could not believe this was paris.
