I booked a room in this apartment for 4 months. The whole experience was a delight.
The flat has 4 rooms in total and you will meet a lot of people coming from all around the world. Those people really added a lot to my stay in Copenhagen. The only downside is when there are more than 4-5 people at the same time it can get a bit crowdy especially for using the kitchen.
The house is really well positioned between 2 metro station in a very calm district. it is very close from the center and takes only 8 minutes with the bike. Whether you come for a long or short stay, I recommend Guillaume's rooms.
Enjoy Copenhagen !
