One more opinion: 3km is definitely too far for groceries, that’s driving distance. It’s half an hour walking each way, the return loaded with bags? Forget about it.
I live on the edge of a small-ish town and it takes me 15 min to the nearest supermarket, and that’s quite a lot, everyone on this streets bikes there, in about 5 min. From there towards the center you don’t need to walk more than 5 min to get groceries.
I’d say having to walk more than a 10 minutes for groceries already affects the apartment value.
And a criminal.
