We spend two nights at the apartment and I would definitely book it again.
The location of the flat is perfect, the shopping street, all the bars and clubs aswell as some sights like the Erasmus bridge and the Markthal are within walking distance.
The flat was clean and was equipped with everything you may need (Coffe Mashine, microwave, washing machine, ...).
The host always replied within a couple of minutes if we needed anything and the check in was super easy aswell.
So go ahead and book this apartment, you won’t regret it.
