We stayed in Astrid's flat for a long weekend in Copenhagen together with our 1 year old toddler. the flat is well located in the nice Vesterbro neighbourhood Vesterbro, close to metro, groceries, shopping, cafes, restaurants, bars etc. walking distance from the zoo and train station which was great for us.
The flat is small but well equipped. the only slightly annoying thing for us is that there we didn't find a good place to park the stroller, so we ended up carrying it up a steep stair of flights and keeping it inside the apartment where it took a lot of space. so maybe bring a foldable one if you're in a similar situation.
Astrid was very kind and super responsive, she also got hold of a baby bed for us, although there normally isn't one. communication was super smooth overall.
