Real Estate Consultant
For Alica Klemp, property is more than just rooms – it is an expression of lifestyle, character and personal values. Based on this conviction, her aim is to advise every client with sensitivity, clarity and reliability.

As a native of Hamburg, she combines her passion for property, design and architecture with a versatile lifestyle – be it skiing or dancing. Just as professionally, she is dynamic, open-minded and full of enthusiasm.

Alica Klemp has been working as a property agent on the Hamburg property market for more than 8 years and knows the subtle nuances between Hanseatic restraint and an exclusive lifestyle.
