Unfortunately we are unable to provide guest apartments.

Please contact us with your meter number via the usual channels. Then it’s up to you: you can be around for the meter reading. In that case, we’ll need your telephone number to arrange an appointment with you. Otherwise, we are also happy to read your electricity meter when you’re out and leave a note with the figures in your letterbox.

Yes, we also sell individual units and buildings. This service is of course commission-free. You can find currently available properties in our portfolio.

The secret to proper ventilation is leaving all the windows wide open a few times a day and creating a proper draught. Ten minutes is usually enough to replace the room air. This also keeps humidity in the room at a reasonable level and you benefit from a healthy indoor climate.

Sorting waste makes sense because the waste finds a new use in the economy – as a raw and base material for new products. If you sort waste thoroughly, you’re protecting our resources. And that’s good for your carbon footprint. If waste is put in the wrong container, the disposal company may also refuse to empty the bins. If a separate waste collection is required, the costs which arise will be charged to the tenant.

Have you changed your name? Please supply us with a copy of the relevant official document. Please note that a copy of your ID is not sufficient on its own. However, if you happen to send us your ID, for data protection reasons, please redact the information so that only your name, photo, date of birth and contact address are visible.

If you discover that a large number of insects or pests such as rats, ants or wasps have appeared in your home or building, please contact us to let us know. The more specific you can be, the better our contracted pest controller can prepare for the situation.

Once you have logged into our customer portal, you can change some of your personal details under “My user account”. If you cannot edit the data you wish to change here, please let us know your request in the customer portal under “Contact” or contact us via the usual channels.
