I honestly don't recommend the appartement. But as always - it belongs to your own requirements and wishes.
Check-In:
Was okay. You have to pick up the keys in a small supermarket near the appartement. Had to repeat the code few times, shop assistant wasn't friendly - but it worked out.
Location is central and directly in Montmarte, near to Metro Station Anvers, but in a small side road. At night, it's loud, but you have to sleep at open windows when it's warm.
The app. itself is very small - works for two people who know each other well.
But it's not clean! Dirt on the floor, corona mask in the wardrobe, lot of dirty spots, and an unsanitary bathroom (btw a very small bathroom).
We tried to improve, but the vakuum cleaner doesn't work. Last evening, we also met a cockroach.
All in all, i get along with small and used appartements. But a housekeeping is the least.
I reported the situation during our stay, and send photos. The only reaction was an excuse. No service or price reduction.
Could have been my last Airbnb stay.
Next time i choose a hotel.
