Unable to answer "What are the opening hours here?" – Veturiaukio (Marketplace) – way/1193393090 via StreetComplete 58.2:

It's a marketplace. It doesn't have hours. Always open 24/7

Koukkupommi?

Must check if this this ditch starts here or earlier, on Google Maps there is some water south from here, there is also a bridge marked on Avijoentie on OSM, so I guess this ditch doesn't really start on this spot, but has its beginnings further down south.

This note is also a personal marker so I can find the place to check it out.

Hei, Kouvola postinumero on 4000 ryhmää, eli tässä olisi 46900 oikea postinumero. Vastaavat virheet olisi hyvä koko alueella korjata

Lisään pyöräparkit mutta pysäköinti ja ulkovarasto pitäisi varmaan myös

Ditch or stream?

There's probably an apartment parking area here, so it could be added.
