Ralf's apartment is lovely. Located in a great neighbourhood, amazing view, very clean and comfortable. But you should be aware that this is not a person to person transaction. You will effectively be renting the apartment from an agency and on check additional documentation needs to be completed with the agency representative (who also charged us $20 for a 'late check in'. If you are OK with this, highly recommended. If you prefer the personal touch of a more conventional airbnb host, look elsewhere.
