I spent four weeks for a work-stay in Copenhagen in Asas place and enjoyed it a lot.
The location of the flat could not be any better - Norrebro has basically everything you need for a nice stay - very close to the flat: all different kinds of restaurants, grocery stores, cafes and bars. You are also close to the lakes on the one and to Assistens Park on the other hand, which both are very nice locations for a chill in the sun. Also Norrebro Station and Torvehallerne food hall (if you are into that) are just a 10 mins bicycle ride away - which in my opinion is THE heart place to reach almost everything else from (Metro, train, Bus to wherever and city center by food from there).
Immediately on the corner of that street of the flat there is this incredible yummy bakery - defenitely go there for a sweet breakfast! next to it there's also a winebar and a burger place! grocery shops are always open til 22pm and are also open on sundays - so you will defenitely find something to shop, eat or to drink at any time of the day within a short footwalk distance.
The flat itself is very cute and cosy and has got everything you need for a long or short term stay. I honestly had to get used a bit to the bathroom being downstairs but it's really not a big deal and as I learned pretty common in the older houses in copenhagen :)
Asa also provided me a bike to cruise around, lights and helmet included - so I did not have to rent one.
She unfortunately could not make it to say hi at my check it but managed to get one of the lovely neighbors to do so. He showed me where everything was and how things worked so I had all the informations when I arrived. Also the bus from the airport stops almost in front of the flat - which is very nice for an easy arriving and leaving again.
Communication before and during my stay was very easy, uncomplicated and she always answered quickly.
So i can higlhy recommend staying at Asas place - especially if you want to get the real hygge experience :)
