Tenant replacement in Birmingham city centre

The flat is in excellent condition in close distance to Birmingham New Street train station (5-8 min). It is a quite (backyard of the building), bright, warm and spacious flat/room. The room has ensuite large bathroom (including bathtub) and also include named parking space in the garage. The bill does not include council tax (free for students).
The current tenant, Dimitris is a 31 yo Greek professional working part time in JLR while doing his PhD in data science at the University of Warwick. He is a kind and communicative flatmate. He is quiet and respects privacy.
The neighbour has a lot of shops, supermarkets, bars and the bullring is in walking distance.
I would like a tenant replacement in any possible date, because I need to move out from the property since I found a new job!
