There were definite pros, but also some cons to Mikkel's apartment:
First of all, the bathroom was just awful, I feel bad to say this, but it is true. The shower was dirty with mold-like patches, and the curtain looked rotten. In three days we did not dare use it because we had no slippers with us.
The rest of the bathroom was pretty okay, but very tiny (I am afraid that if you are plus sized you will have a hard time using the toilet).
There was absolutely no space to place our things, not in the bathroom, nor anywhere else in the apartment. We had to leave everything on the dinner table or in our suitcase.
Lastly, Mikkel gave us one towel each, but they both had stains on them.
Now for the pros:
Number one has to be location, it takes about 15 minutes by foot to get to the Little Mermaid, but about 40 to be in the city center. Mikkel informed us that you could rent a bike nearby, but we only used public transportation. The train comes every 2 minutes and you're in the center in an instant. Same goes for the airport, it takes 30 minutes total.
Mikkel has two TV's in his apartment, one in the bedroom, which has Apple TV, and the other one was in the living room which we haven't used. We brought a usb stick with films on it to watch on the bedroom's television.
A big plus for the dishwasher and laundry machine. It was just a bit weird to find dirty dishes in the dishwasher when we arrived, but I guess that's okay.
Just a reminder that you have to go up three flights of stairs because there is no elevator.
Mikkel was a great host. I contacted him about a week upon arrival to set a check-in time (I could come at whatever time I preferred). The same for the check-out, Mikkel had no problem with the time. We did a self check-out, so we did not see him again, but he sent me a message asking me if everything was going well in the apartment!
