Columba’s flat is in an old apartment building with thin walls in a quiet residential neighborhood so I would say be aware that there is a strict no-noise policy after 11pm (including no baths/showers and use of the parking garage) for consideration of the neighbors and other guests. We arrived late after midnight for check-in which almost caused an issue but Columba received us in the end. I would say the check-in time is between 2-11pm in practice due to the no-noise policy. The location is about a 45-50 min leisurely walk to the old town which was doable for my partner and I. We enjoyed the fruit yoghurt and toast breakfast prepared by Columba. The room and shared shower was also very clean.
