A wonderful holiday in København! A friend and I (25year olds) stayed in Alex's apartment for 2 nights. Alex was communicative and clear throughout booking, even though I was late in replying to him (sorry again). He even asked us what we wanted to see and researched lots of places which turned out to be fantastic (Mother & Höst restaurants, the Kødbyen bars). He met us at the apartment and even messaged us during the holiday to check everything was ok.
The apartment is spacious and bright; we used the sofa bed too which was fine. There's even a PS4 to play/watch DVDs after big nights out. The kitchen had been renovated and although we didn't use it, it seemed workable. Lots has been said about the "small bathroom"; Alex tackled the subject head on, explained why the bathroom is so small & we didn't find it a problem at all.
The apartment is located in the Islands Brygge area. It's quiet and friendly and the apartment overlooks the water. We rented bikes (on Alex's recommendation) and cycled everywhere, which we found safe, simple and a hilarious experience (especially after a few drinks in Kødbyen).
