I stayed one night at Per's place and liked the place and the conversations with the host a lot. He is very helpful, eager to give very useful tips. The place is wonderfully clean and very "hygge" 😉 not in the center, but there are two citybus stops 5 minutes away and a metro station within about 10-12 minutes of walking distance. If you find Copenhagen expensive and are low on budget, there are Lidl and Aldi supermarkets a couple of minutes away
