Will be traveling with two friends for 4 days in Copenhagen and we are looking for a hotel that accommodates three adults in terms of providing 3 single twin beds. Places I am finding have a double bed and a twin. Help!! any recommendations?
Cabinn has a small number of "standard family" rooms with four single beds (two of which are upper bunks). See the pictures here: https://www.cabinn.com/en/hotel/cabinn-city-hotel The rooms are pretty small, though, so they wouldn't give you much room to spread out.
The Cabinn Scandinavia branch has "commodore family" rooms which may be a bit better for you: https://www.cabinn.com/en/hotel/cabinn-scandinavia-hotel
The Danhostel Copenhagen City has rooms with two twin beds and foldable bunk beds. http://danhostelcopenhagencity.dk/en
I've found the best way to find triples is to go to booking.com and enter 3 Adults in the search box directly under the dates and number of rooms, you will see many options for triples. Some of the options may include double/queen beds and a twin/sofa bed assuming 2 people can share but many will have 3 twins, twin and 2 bunk beds or 2 beds with a sofa bed. Some with triples include: Saga Hotel, Zleep, Grand Hotel, Annex Copenhagen, Richmond Hotel, Copenhagen Island (w/sofa bed), Ascot Hotel, Mercur.
If you're open to an apartment, airbnb has an option to filter for the number of beds.
