We had a good stay overall.
We had some issues when we arrived (broken entrance door, French press missing) but we've talked them through with the host so I won't go over it here. The host ended up providing us with solutions.
I'm very mindful of cleanliness and the flat was overall clean (except for some cereal containers in the kitchen and some dishes that weren't perfectly washed).
The flat is nicely furnished, with comfortable bedding (we were a family of four and used both the bedroom double bed and the living room sofa bed).
The bathroom is spacious with a large shower, which was super nice.
If you're not used to living in a big city, you may find the flat noisy (it's on the street side, so obviously you can hear a bit of traffic). But to me this wasn't at all an issue.
