I have 2 small rooms vacant with double beds.
I am a non smoker...so it is a non-smoking apartment.
If you come from the Airport, you just take the Metro (15 minutes) to Christianshavn, (remember it is 3 zones) and then you walk for 5 minutes. By train you stop at Norreport station and take the Metro to Christianshavn.
All en all it take an hour from you land, until you are at my place, depending on the luggage.
