A flat roomy enough for ten people right in the city centre is pretty much unheard of, so imagine our surprise when we found this gem. With five stylish bedrooms and an amply-sized living area meant for socialising, there's enough space here for a big group to spread out and get comfortable. The kitchen isn't massive – we'd only recommend it for cooking breakfast and other light meals – but we liked the vanity area outside the bathrooms, where you can prep hair and makeup without hogging the loo. There are other touches, too – USB plugs by all the beds, an Apple TV in the living space for at-home movie nights and no single-use plastic. This building has the highest eco-certification (A15) and it's run on renewable energy, so it's as good for the environment as it is stylish. Best of all is the location – Strøget is just around the corner, with restaurants, shops, cafes and bars all right on your doorstep. You're only two minutes away from Kongens Have and Rosenborg Castle as well, perfect for strolls in the sun.

Home truths:
*Four of the beds can be split into two singles on request
*The kitchen is very small – it's only really equipped for cooking light meals and snacks, not feasts
*When we visited, the wifi wasn't very fast
*None of the bedrooms have a lot of space for unpacking suitcases and they all have glass partition walls that separate them from the living area – there are curtains, but it's not super private
*Even though there's a lift, you have to climb four steps to get to the front door
*There's no in-person check-in – your keys will be left for you to pick up in a lockbox
*The walls could do with a lick of paint to cover up scuff marks
*The host can arrange a cot if needed
