Sorry mate, not going to spend much behind this. Going for a cheap single-door only.What model have you decided on? do you have a shortlist
A double door prevents the freezer from getting exposed every time you open the door. Compared to a single door.
Since you need a freezer a double door is better.
This is the only one which I find 'acceptable' in teams of aesthetic:

Just wish it was slightly larger (above 200 litres just for the sake of future proof) and 5 star rated. Aesthetic becoming the main hindrance while choosing a model, all come with juvenile flowery design, and those which are plain are glossy!
