The flat is nicely decorated and overall clean. Harold is friendly and accepted that we leave our luggage until 4 pm on the day of check out and collect it later.
However there few negative points that may put you off, depending on how you are. There were towels of previous guests left in the washing machine and a wet towel in the bath when we arrived. Coffee maker was also left unclean and full of coffee. The bathroom smells like mold and you see mold on the edge and on the curtain. We kept the door closed and windows of other rooms open.
The area is more a poor and run-down part of Paris with a lot of ethnical shops. There is a very nice Canal with cafes 5 mins walking and the metro is around the corner. But we made a mistake and walked in the evening towards sacre coeur. It was scary and very sad. Loads of homeless people sleeping under the bridge and lots of young scary guys standing on the streets. This is NOT the romantic Paris you may imagine.
