Joachim’s place has an ideal location, which is very central and close to all the beauty and great things that Copenhagen provides. The appartment/studio is clean and provides much comfort. Maybe the bathroom could use a renovation but it does what it needs to, which is the most important thing.
Also note that, if you are a light sleeper please bring earplugs because there are some bars in the street which can cause nighttime noise.
TL;DR: Joachim is a great and very communicative host. The appartment is perfect and clean for a comfortable city trip. It is a high recommendation!
