Despite originating from Italy, these instruments became really popular in France in the 19th century, and soon, cafés and cabarets in the country were filled with the sound of these instruments. During the 1930s, the accordion-heavy bal musette became incredibly popular, and this music style is linked to traditional France in the collective mind to this day. It isn't rare to find beggars or street artists playing accordion in the Parisian subway or in the streets even now.
On a side note, accordion is part of some non-Parisian French regions' traditional music such as in Alsace (where it sounds closer to Polka and German brass band music, for historical reasons), but it's as rarely featured in fiction as non-Parisian areas of France are, and thus bal musette/waltz-style accordion music dominates in fictionland.
Despite the tendency to associate accordions with France/Paris, the instrument is far from exclusive to that country. South American countries like Brazil or Colombia and most especially Argentina with the tango scene, as well as Eastern European countries are rather fond of it as well, but this fact isn't as widely known as France's case. The largest non-French accordion usages most people are likely to recognize are polka music, tango music and sailing music.

But the next line is a different character saying "I must say I won't be entirely sorry to leave Lambeth— the river smells like a dead cat, and the accordionist downstairs is driving me insane".
