Five of us, ranging from 23 to 62 yrs old, stayed here in early June 2018. As others mentioned, it's a 6-floor walk-up which isn't that big of a deal if you're prepared for it (a couple of us with larger bags got help from others in our party). This generally kept us from going back to the apartment except when heading home for the night, but as we were visiting to see the city that wasn't really an issue. The apartment is well-curated and stylish; somewhat spare in the Scandanvian way (which we like) but has just about everything you need (including a wonderful turn-table and great LP's, which may be played if handled with care). We actually didn't meet Kristian in person as he was out of town when we were there -- a friend of his met us at the door to give us the keys -- but he was an excellent communicator, responding immediately to questions via email and/or text, and checking in every day or two to make sure we were happy and had everything we needed. It was very hot (record heat wave) when we stayed; this is a pretty unusual circumstance so there was no fan in the apartment, but we kept the shades closed during the day and opened the windows to get cross ventilation at night and this made it pretty comfortable. The apartment would be perfect for four and is good for five if you're okay with someone sleeping in the living room on the couch (which we were). There is one bathroom and it's pretty small. The place has a nice view of rooftops and a sweet courtyard garden out back, although we didn't have access to that area. Vesterbro is a great neighborhood if you want to stay somewhere that's not overly touristed -- wonderful cafes and small shops nearby, and only about 10 minutes by bike into the center of the city. And, as the apartment is at the top of the building, there is no noise from any floors above and the street noise is not really an issue (unlike for some of our friends who stayed in the Latin Quarter while we were there -- they were kept up all night by revelers). All in all, I recommend this place.
