We had an amazing stay here with our 1.5 and 4 year old. Susanne was super helpful and communicative. The apartment is not huge but it's very functional and a great stay for the 4 of us. The location is very convenient - near the metro, prater amusement park, playgrounds and safe bike paths. The one thing we didn't love was not having a gate for the stairs, especially because the steps are skinny, but we were easily able to block it off ourselves. Would definitely stay again!
