Harvestehude
Along the Alster in Harvestehude stand villas and large period apartments, and clients are wealthy, often older, and value discretion. Enquiries come by email, in full sentences with a proper greeting, and expect a reply in the same tone. Draft mode pays off here: the AI receptionist writes the suggestion, you adjust the wording and send it. Longer treatments are booked for the morning. A deposit at booking is accepted here as well, as long as it is explained politely.
