Looking for 2-bedroom apartment starting in October

Hola!! My sister and I are moving to Madrid for a year as auxiliares de conversación. We're searching for a 2-bedroom apartment from October to July. Open to sharing a 3 or 4 bedroom place with girls around our age too (we are 22 and 23). If you have a place or know someone renting, please let us know. Thanks a lot! ????????
