The apartment is very small (as written in the listing) but well organized. if you plan to cook, be aware that there is no space where to cut and prepare except the small table where you also eat. the sofa and bed are comfortable (but the bed is smaller than a normal king size). the bathroom is small but well structured, in particular the shower is spacious).
personally we found the apartment clean but not very thoroughly (especially bath towels with some spot and a strange smell, and same for the blanket). we really enjoyed the location because it's near a lot of metro stations and you can also reach the train station by foot in 20 min. there are also a lot of nice restaurants and bars nearby.
overall it's a great apartment for a quick visit in town. for longer periods (we stayed a full week) it is a little bit too small and uncomfortable (for example we didn't have a broom so it became a problem after a few days).
the hosts are helpful and the check-in is easy.
