Large double room for sisters wanted

Hi, I'm Lumi and I'm looking to rent a large double room to share with my sister, in Portsmouth university area. We don't mind walking so it can be at 20-25 minutes from uni.
We're both mature students ( 25&28 ) and we'll be working part time during our studies.
We're pretty quiet and kept to ourselves, but also easy going and relaxed. Clean and tidy, organised and respectful.
No drinking, no smoking, no clubbing, no drama. We're both Christians and preferably would like to have like minded flatmates/roommates. Preferably females only. Our budget is around £600-650 with bills included.
Please do message me if you have a room for the both of us or if you want to buddy up and rent a whole house/flat together.
Thanks ! 😊
Lumi
