Mathiaes is obviously one of the best host whom I encounter - extremely responsive throughout the process, very willing to offer assistance whenever it’s required. His apartment is at the heart of Copenhagen - most tourist attraction are within a 10 - 15 mins walk away from the location and is the place is extremely well connected by all public transportation.
Only downside is the pretty narrow staircase - which if you are carrying a huge luggage it might take you some effort to move the luggage up, but guess the perk is you get to stay at the top floor, which is pretty nice!
