As soon as you are on the space you want to book, you can select the desired time window on the time axis (hold mouse).
The price is calculated on an hourly basis if the space can be booked on an hourly basis. If you wish to book the room for a half-day / daily package and the space is free, you can click on the right under the calendar on "Select time" and select the correct entry (see question "How is the price calculated?").
In the case of an instant booking, you can carry out the entire booking process independently and do not need the consent of the provider. Once the process is complete, both parties will receive a booking confirmation (PDF) via email, which is also available online under "My bookings".
In the case of a booking request, the latter is sent to the provider. There, you can specify additional information or ask the provider questions. The provider can then answer questions and clarify the last details, which are all sent by email and can be seen under "My messages". Once everything has been discussed, the provider can make you an offer and adjust the price and the times if needed. You can then complete the booking process.
