Mathias Apartment has a perfect location, you'll get anywhere in Copenhaguen within an Easy walk. He couldn't be able to Check us in, but His parents did and were very nice and helpfull. They left us lots of info with restaurants and pubs recomendations, Also tivoli tickets and some ear protection so that We can sleep well beyond the noise in the street (The Area has plenty of nightlife).
The apartment is very confortable and cozy, we spend very nice moments in it. Would be staying there at our next trip to Copenhague, thanks Mathias!
