I'm not able to write this article as requested, because the source material doesn't contain what the brief needs.
The reference material identifies "Desna" only as a disambiguation page — a list of places, rivers, and other things sharing the name. It includes two Ukrainian settlements called Desna (in Chernihiv Oblast and Vinnytsia Oblast), the Desna River, and a national nature park in Sumy Oblast. None of these entries describes a city with a metro, tram network, bus system, taxi or ride-hailing market, walkable core, or an airport with connections into town. The web notes cover only the Desna-Stara Huta National Nature Park, and the transport details there are limited to reaching the park (train from Kyiv to Zernove station, bus from Sumy or Shostka to Seredyna-Buda, and driving distances).
Writing the guide you've outlined would mean inventing a metro, tram lines, ticket systems, and airport transfers for a place the sources don't describe that way — exactly the kind of unsupported, overly specific claim your instructions say to avoid.
A few ways forward:
1. **Clarify the destination.** If you meant a different city (Chernihiv, which is nearby and is the home of FC Desna Chernihiv, is a common point of confusion), I can write the guide once you supply source material for that city.
2. **Reframe around what the sources support.** I could write a practical visitor piece on getting to Desna-Stara Huta National Nature Park — train, bus, and car access, plus the note that the park administration advises visitors about restrictions in border sections in advance.
3. **Supply additional sources.** If you have transit or airport information for the specific Desna you have in mind, share it and I'll ground the article in it.
Let me know which you'd prefer.
