The Vesta micro-app from eeproperty allows you to book one or more washing machines and pay for their use.
Additionally, you can conveniently top up your credit via app.
The booking of a washing machine is done through a schedule where free, blocked and the self booked periods are visible.
You can see in the micro app which washing machines are currently available.
This reservations-based approach significantly simplifies the process and also lists previous bookings and payment transactions in a clear manner.
