Location: brilliant! Quiet street, close to public transport, Canal St. Martin at the end of the street. Smallish (as advertised), clever solution for bed.
But:
Nowhere to put or hang coats, clothes or towels. There is a wardrobe, but locked.
The flat is on the 5th floor (USA: 6th) with a fairly steep spiral staircase. The ad should have mentioned that.
The place was clean, except for the toilet that was stained dark brown and yellow.
We experienced difficulties with the door codes and the internet, but these were solved.
The host is kind and helpful, but from my perspective he is not professional enough (yet?)
