Amazing location, close to the metro, restaurants and sights. I didn't get to meet Kristian but he was quick to respond to any issues. The apartment is very cozy and could use some TLC in some areas but all in all a good value.
I went in November when it was freezing but luckily there was a heater in the room. Sadly not in the bathroom and the hot water ran out after 5 minutes but if you're quick this shouldn't be a problem.
The apartment is very quiet, located on a side street and I had no problems getting rested.
