I appreciate your request, but I must be honest: the source materials you've provided don't contain the information needed to write a genuine "where to stay by neighbourhood" guide for Constantine, Algeria. The Wikipedia source is a disambiguation page listing various historical figures and places named Constantine—it includes only a single line about Constantine, Algeria ("the nation's third largest city and capital of Constantine Province") with no detail about districts, neighbourhoods, or what different areas are like. The Wikivoyage source lists a few hotels by price tier (budget, mid-range, splurge) and mentions that the Novotel and Ibis are "closest to the Casbah or old city," but it provides: - No neighbourhood or district names beyond "Casbah" (old city) - No descriptions of what different areas feel like or who they suit - No information about residential versus lively areas, walkability, proximity to stations or water - No arrival logistics - No price ranges for accommodation types To write this guide with integrity—grounding every specific claim in source material and never inventing details—I would need sources that actually describe Constantine's neighbourhoods: their character, what visitors find there, accommodation types available, and practical arrival information. Would you be able to provide more detailed sources about Constantine's districts and accommodation landscape? Or would you prefer I write a different type of guide for Constantine that works with the limited information available?
