Is this museum open or not. I read a traveller review from February 2018 however the next reviewer states it is closed until 2020.
The little yellow house is still open! The old Hans Christian Andersen Museum is closed due to renovation, but a Andersen museum has opened in its place very close by (2 min away) - at Claus Bergs Gade 11, 5000 Odense C. Opening hours are Tuesday to Sunday, 10am to 4pm. I realise this reply is late, but might help others :)
