Birger's place is excellent and extremely clean. It is a huge place where we, traveling as a family of 4, could spread out and relax without being on top of each other.
My 9 year old daughter loved the courtyard. She wanted to go all the time. It's a huge space that really impressed my local friends.
For being in such a central location, the place was very quiet. Street noise is muted and we rarely heard the neighbors. Note that the place is on 5th floor (US counting) / 4th floor (Euro counting) with no elevator, so you'll be climbing stairs. It's a wide and very comfortable staircase and for us, the place was easily worth the extra exercise.
Above all, the location is incredible. Of all the "brokvarter" (neighborhoods surrounding the city center) in Copenhagen, Vesterbro is the most lively and eclectic IMO. This place is in easy walking distance to everything you want to do in Vesterbro. At the same time, it is also in walking distance to the city center with Tivoli, Strøget (walking street), etc. It's very hard to find a place like that.
Birger did an excellent job with communication via AirBnB messages. He personally welcomed us which is always a nice touch and he promptly answered any questions we had leading up to the stay.
