We loved Copenhagen as a city and staying at Jonas' place overall worked out great.
Check-in: not bad. I didn't have access to my phone and needed to go to a cafe to get wifi to contact Jonas as he did not answer when we rang the door.
Cleanliness- not sparkling clean but definitely tidy.
Bed- quite uncomfortable. The mattress was thin and stiff. Also, the towels provided were small and stiff as well. (not a main concern for me as we were only there a few nights, but might be worth it to know for someone considering a longer stay).
Kitchen- well equipped kitchen. We cooked one night and found everything we needed.
Bathroom- not ideal but manageable. It's in a basement that feels more like a dungeon. Definitely wish I brought flip flops. It was kind of an uncomfortable experience, but not a huge issue.
Location- perfect. There are cafes, bars and grocery stores all within walking distance. We rented bikes (a must!) and got around to other parts of the city in 10-15 mins.
Side note- Jonas has an awesome record collection that we thoroughly enjoyed!
Thanks for everything, Jonas! :)
