Pros:
Spacious apartment.
Host replies fast.
Provided good sound system with good quality steamer which made it a breeze to straighten out crumpled clothes from the luggage.
Cons:
Nil curtains. (Felt very uncomfortable with neighbours peering in and therefore, had to close the outer windows which left the room really dark as indoor lamps were quite dim)
Nil sofa.
Nil hairdryer and I had long hair so my hair couldn't dry. Those with long hair do take note.
Floor was gritty and feet were black from walking around barefooted.
Nil bidet as listed initially.
Duvet had a single linen on top and not a duvet cover. Which I felt was unsanitary.
Note that there is no elevator and when there is no daylight, you will have to navigate through almost pitch black darkness down/up 4 storeys of long winding stairs. (Floors start from 0) which bothered me alot as my luggage was extremely heavy.
Felt uncomfortable with the neighbourhood as spelt by the other guests. Nearest metro stations are Stalingrad and La Chapelle. You may want to read up on this neighbourhoods.
All are from own perspective and experience which may differ from the others so do make your own assessment.
