Mette's place is just wonderful! The apartment is lovely, it is clean and airy and has so much personality running through it, such a great place to be especially after a long day sightseeing! Mette was very welcoming and accommodating, we arrived late in the evening and followed the instructions to get the metro and bus, it was easy and there were no problems at all.
The local neighbourhood is incredibly vibrant and full of places to eat and drink - we were there 5 nights and had breakfast in a different cafe each morning, all outstanding and within a few minutes of the apartment. I would highly recommend staying here, the area is very popular and quite trendy with the locals. We far preferred the local restaurants etc. rather than the centre where it is very touristic.
Copenhagen central station is only about a 15 minute walk away, and the walk along Sønder Blvd is great! So many quirky places to see along the way. We would also highly recommend Absolon, it is an old church on the main boulevard that has been converted into a kind of community centre with a bar and games etc. It is very popular with the locals. Each evening they hold a community dinner at 6pm where everyone sits down together in the hall to meet and eat amazing food. Such a good experience and a great way to meet some friendly Danes.
We would also recommend hiring bikes, if you are brave enough! There is a rental shop just a few blocks from Mette's apartment and the price is quite reasonable. Before setting off I would check out YouTube for an example of 'the Copenhagen left', making a left turn was baffling! Hiring bikes really opened up the city for us. A few great locations: Frederiksberg Gardens (close by), Bakken Amusement Park - forget Tivoli Gardens - Bakken is the world's oldest park, operating since the 16th century! (It's bit or a ride up to the north) also Amager Strand has a lovely beach and it is not far at all.
Finally, thank you again to Mette for making our stay so perfect. Copenhagen is such an incredible city and it was great to have a friendly host to give us a head start.
