We were a group of friends travelling to Copenhagen for a weekend trip. The location of the place was excellent, close to the airport, and reasonably close to the city. I can imagine it being very nice in the summer as it is close to the beach as well.
Lasse's house is amazing and very stylish. The house is spacious, and very clean. We were 8, and it was more than enough space for us. Three bathrooms are also perfect for a larger group. The kitchen is well equipped for making breakfast and dinner.
Lasse responds quickly to all inquiries, and is an excellent host. If you are going to Copenhagen, I would definitely consider staying at Lasse's house!
