Fantastic stay, the unit is small, as described, but was perfect for me as a single person.
The heating worked perfectly and the humidifier also helped a lot with the dry winter air.
The place is in a fantastic location with public transport stops within 5 minutes. Gregor had great communication with excellent recommendations for Christmas markets and attractions, and gave very clear instructions to access the unit
I will highly recommend this unit if there are no mobility issues, and highly recommend Gregor as a host.
