We stayed one month in Anna's and Fonzy's apartment with my husband and 19month old daughter. Even if the flat is small we still had plenty of room. You've got all the necessary stuff available with nothing extra taking space.
The apartment is suitable for a family. The house has an elevator that can fit a stroller and there's enough room to store it inside the flat. No need to even fold it!
Our daughter enjoyed the bathtub and large sofa.
Location is great! And the hosts very helpful and nice. If we ever move back to USA we'll surely book this one again.
