We had a really lovely stay at Carl's place. It felt home from home. It's well served by local bakeries, small supermarkets, bars and restaurants. We walked most places and worked out which days had free entry into the galleries so there was no need to buy a Copenhagen Card! We took a train ride out to Louisiana, which is our favourite gallery. I highly recommend a day out there.
The square at the metro entrance isn't great but we felt very safe everywhere else.
