We had a very pleasant stay at Casper and Lilli's place. It's located in a good neighborhood where you can find many things needed; two supermarkets at a 100m distance, various cafe and restaurants nearby. And just 10-15 minutes far from center by bus; close to a 5C bus stop (this line functions all day/night and takes you to centrum and central station). Also it only takes around 20 minutes to walk.
We met Casper's friend at the bus stop, he showed us the house and left the keys. There was a note from Casper and Lilli that is giving some nice tips. Casper was helpful and easily reachable via e-mail.
Apartment's location is perfect and it has everything that you might need. The house was clean, fresh linens and towels were available. The bathroom was quite small (as most of the other CPH apartments) but not that hard to take a shower. There was no base for the bed but the mattress was comfortable. Although we didn't cook, the kitchen was fully equipped. Balcony was nice.
We haven't encountered any problem at all, and would think of renting again in case of visiting CPH again.
