We were a group of four and have spent three great days in Copenhagen, staying at Christian's place. It is very well located, close to bike rental stations and also within walking distance of the inner city - a great base for exploring Copenhagen! Christian has one double bed and several matresses, and the appartment is very light and roomy. One thing to consider is that it is directly at a main road, so it is not recommended to sleep with open windows. But if you're looking for a central, friendly and big flat with lots of shops, restaurants and cafes around, this is a fantastic option!
