On the positive side, the apartment is in a great location - close to the metro, and with lots of good places around to eat out in (and great bakeries!). The bed was also reasonably comfortable for a sofa bed; and the appliances in the kitchen are modern and work well. Emil (and his friend who met us when we arrived) communicated well and was positive a quick to respond to our texts and emails.
On the negative (and we have provided feedback on this to the host), the apartment left a lot to be desired in the cleanliness stakes; and we felt the listing was quite misleading. The "bathroom" consists of a toilet with a shower nozzle beside it (I've seen bigger bathrooms in trains :-() and there are 4 flights of stairs up to the apartment that weren't mentioned in the listing. We checked out early to stay elsewhere in Copenhagen and would have done so earlier if we had been able to afford it.
