Bertolinette is an obscure character piece reflecting the salon style of the late 19th century French piano school. It relies on melodic ornamentation and a sentimental expressive language.
The primary challenge is balancing the lyrical melody against a somewhat busy accompaniment texture.
Comparable difficulty and character — good candidates for what to learn next.
Bertolinette (Op.110) is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 5.
You should be comfortable at Henle level 4 — meaning you can already play level 3–4 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
