The place is great in every way! The location is quite central and also super close to the Metro. It was also very clean and cozy, very good for two people.
The host was very friendly and always replied super fast. When we arrived earlier than the planned check-in-time, it was no problem for us to check in sooner via the keybox, which was incredibly useful and nice!
The only thing was that the heating did not work, but it was no problem, as you could just run the AC which would heat up the flat too! Shower could go to very hot temperature, which was very pleasant in February :)
